BOM Remover strips exactly one leading U+FEFF Byte Order Mark from a string of already-decoded text, leaving every internal, trailing, or second-leading occurrence exactly where it was. The check is binary: it tests whether the first UTF-16 code unit equals hexadecimal FEFF, and if so returns input.slice(1). Otherwise it returns the input string unchanged. All processing happens in the current browser tab; the pasted text is never uploaded, and no external service sees the content. Because the tool operates on decoded characters in a textarea, it cannot read raw bytes, infer the original file encoding, or detect whether a source file ever contained the EF BB BF, FE FF, FF FE, 00 00 FE FF, or 00 00 00 00 FE FF signature. Position is the entire rule, not content or frequency. The input may hold up to 200,000 UTF-16 code units, the output has an independent 200,000-unit cap, and editing the input clears previous results so an over-limit error cannot leave a stale successful output on the page.
If your search was driven by a Grand Theft Auto V session — looking for a way to remove a sticky bomb from a sports car or trigger a vehicle explosion — this tool will not do that. The in-game behavior of vehicles, sticky charges, and personal aircraft in GTA V is unrelated to text encoding, and no character on the keyboard corresponds to a "remove bomb" dev command. What frequently happens instead is a sound-alike or typo mix-up: someone copies a JSON mod config, a trainer export, a Social Club log, or a pasted script fragment into an editor or parser, the very first character turns out to be invisible, the parser rejects the file or silently misreads the leading token, and the symptom gets described as "there's a bomb in my text." That invisible character is almost always the Unicode code point U+FEFF, and a deliberately narrow tool like BOM Remover is built to remove exactly one occurrence of it from the front of a decoded string and nothing else.
Why a 'Remove Bomb' Search Lands on a Developer Tool
Search engines and autocomplete do not separate homophones cleanly. The acronym BOM and the word "bomb" differ by a single character and sound identical in most pronunciations. A developer reading an error message that begins with an invisible character will sometimes describe it as "a weird leading character," "a ghost byte," or "a bomb at the start of the file," and search accordingly. The real culprit in those descriptions is almost always the Unicode character U+FEFF, whose name is ZERO WIDTH NO-BREAK SPACE but which historically carried byte-order-mark semantics at the initial position of a decoded stream, per the WHATWG Encoding Living Standard.
GTA V itself does not expose a U+FEFF to players during normal play. Where the Byte Order Mark does show up in GTA-adjacent work is in user-generated files: trainer configuration JSON, mod manifest files exported by community tools, telemetry logs from third-party launchers, and copy-pasted Rockstar launcher output. A common path looks like this:
- A trainer exports a JSON file that PowerShell's Get-Content reads with the EF BB BF UTF-8 signature still attached.
- The file is saved by a basic editor that preserves the signature rather than stripping it.
- The user pastes the same string into a web validator, a Node script using JSON.parse, or a Python source file starting with a shebang.
- The validator flags an "Unexpected token" or "Invalid character" error because the leading U+FEFF makes the first token start with an invisible marker rather than the expected { or #!.
- The user, possibly a GTA modder themselves, types "how to remove bomb from car gta 5" into a search box because that is roughly how the phantom character feels to them.
BOM Remover is the right shape of intervention at that point because its contract is narrow enough to be predictable: at most one leading code unit is removed, and every other character — CRLF line endings, surrogate pairs, emoji, combining marks, NUL, later U+FEFF, and non-Latin scripts — is preserved bit-for-bit by an exact slice operation. There is no trim, no normalize, no global replaceAll, and no regex pass.
Strip a Leading BOM From Pasted Text in Your Browser
The interface runs entirely in your browser and accepts up to 200,000 UTF-16 code units of input, with the empty string being a valid no-change case. The output panel has an independent 200,000-code-unit limit. Follow these steps for a typical cleanup of paste output that contains a single stray leading U+FEFF.
- Paste already-decoded text into the input area, including the invisible leading U+FEFF if it is actually present. Most browsers render the character as zero-width whitespace, so you cannot see it, but its code point sits at position zero of the JavaScript string.
- Click the run button. The implementation reads input.charCodeAt(0) and compares the result against hexadecimal FEFF — nothing else about the string is inspected.
- Read the status summary. It states whether one leading U+FEFF was removed or whether none was found, and it reports the complete output length in UTF-16 code units.
- Review the full output panel, including line endings, any intentional later U+FEFF content, and the rest of the text. The transform is intentionally a single slice, so anything you did not intend to lose is still there exactly as it was.
- Copy the result locally. Clipboard access is asynchronous and guarded by a generation identifier, so editing or clearing the input invalidates a pending copy rather than letting stale "Copied" state linger on the page.
If the status says no leading U+FEFF was found, the output panel is identical to the input and you do not need to copy anything back to the original file. If the status confirms a removal, the change is exactly one code unit. Two consecutive leading U+FEFF code points will only have the first removed by default; the second then becomes the new first character of the output, and running the tool a second time would remove that one. Empty output is still a valid result — it simply means the pasted string was a single U+FEFF and is now correctly empty.
Input and Output Behavior at the Boundary
The tool's transformation rule is small but precise, and the table below describes how each officially exercised input pattern is handled. The values are drawn from the implementation's executable tests rather than inferred from category norms.
| Input pattern | Output after running | Status summary |
|---|---|---|
| U+FEFF followed by "Hello" | "Hello" | One leading U+FEFF removed |
| "Hello" with no leading BOM | "Hello" | No leading U+FEFF found |
| "He" + U+FEFF + "llo" | "He" + U+FEFF + "llo" | No leading U+FEFF found |
| "Hello" with trailing U+FEFF | "Hello" with trailing U+FEFF | No leading U+FEFF found |
| U+FEFF + U+FEFF + "Hi" | U+FEFF + "Hi" | One leading U+FEFF removed |
| Empty string | Empty string | No-change case, valid |
| Single U+FEFF only | Empty string | One leading U+FEFF removed |
| "Line1\r\n" + U+FEFF + "Line2" | "Line1\r\n" + U+FEFF + "Line2" | No leading U+FEFF found |
Several details follow from these examples and are worth surfacing. First, the result panel always renders, including when output is empty — an empty panel is a successful transformation for a BOM-only input, not a missing or failed operation. Second, CRLF and LF line endings, NUL bytes inside the text, surrogate pairs, emoji, accented characters, and combining marks are all preserved verbatim by the slice operation. Third, the output length reported in the summary is the length of the final string in UTF-16 code units, which is the same unit the limit check uses, so a boundary-exact input is accepted and a boundary-plus-one input is rejected before processing. Fourth, browsers may visually normalize how some invisible characters look in a textarea, but the JavaScript string produced by the logic is the original string minus at most its first U+FEFF code unit.
Limits, Encoding, and What the Tool Does Not Do
BOM Remover is built around one rule, and that narrowness is the point. It does not strip every zero-width character. It does not normalize Unicode. It does not trim whitespace, fold line endings, or rewrite quotes. It does not look at the original file at all, because a browser textarea already contains decoded characters rather than the byte signatures a decoder would normally consume. Encoding detection and signature handling are responsibilities of the decoder, not of post-decode text tools, and the WHATWG Encoding Living Standard treats that division explicitly.
The 200,000-code-unit cap on input and the independent cap on output are deliberate. A valid input cannot expand during processing because the only transformation is removing zero or one code unit, but the output boundary is still checked explicitly as an invariant. Editing or clearing the input immediately clears the previous result, error message, removal flag, copy confirmation, and any pending clipboard timer — so an over-limit error cannot leave a stale successful result visible on the page. A late clipboard permission response cannot restore a "Copied" state once the request has been invalidated by another user action, and a denied request leaves the full read-only output available for manual selection.
For these reasons, BOM Remover is not a substitute for choosing a decoder with the right BOM policy at file-load time. If you can configure PowerShell, iconv, Node's fs.readFileSync with the correct encoding, or your editor's save dialog to suppress the BOM at write time, that is the cleaner fix. Reach for BOM Remover when a trusted decoder has already exposed the leading U+FEFF inside a textarea and that code point is interfering with a parser, comparison, JSON parse, shebang line, CSV header, or column name that needs the very first character to be something else entirely.
When BOM Remover Fits vs. Other Approaches
The tool earns its place in a developer's workflow in a small number of recognizable situations, and three concrete triggers cover most of them.
- You pasted a JSON file from a Windows PowerShell Get-Content call into a web validator, and the first token silently becomes U+FEFF instead of {, producing a parser error at line 1 column 1.
- You copied a CSV header from an export into a script, and the first column name no longer equals the same string without a leading BOM, breaking a join key or a header-driven lookup.
- You saved a Python or Node source file starting with a UTF-8 BOM, and a shebang line is being ignored or a documentation tool is misinterpreting the first character of the file.
- You need to compare two decoded strings for byte equality and one of them carries a BOM that the other does not, so a naive equality check fails despite the visible content matching.
For text pasted from a different enterprise system, a separate guide describes the same cleanup operation in that specific SAP workflow. For file-level stripping on Windows .csv or .txt files that contain a UTF-8 BOM you want to remove at the byte level rather than the decoded level, a different approach is more appropriate. For typical in-browser handling of decoded text where the leading U+FEFF is the only thing standing between you and a successful parse, though, BOM Remover's narrow contract — one leading code unit removed, everything else preserved, no upload, no asynchronous surprises — is exactly the shape of intervention the situation needs.
