To remove special characters in Outlook mail, paste the text into the Special Characters Remover, pick symbols-only or symbols-plus-punctuation mode, and copy the cleaned result back into your Outlook draft. Outlook does not provide a one-click way to strip stray Unicode symbols from body text; its built-in formatting-marks toggle only hides paragraph and tab indicators inside the composer, it does not delete the underlying characters. The tool solves this by matching Unicode's standardized P (punctuation) and S (symbol) categories, so it catches currency signs, arrows, mathematical operators, many emoji, and non-Latin punctuation that an ASCII blacklist would miss. Cleanup runs locally in the browser, so the message you intend to email never leaves your machine, and you see the exact removed-code-point count next to the cleaned text for a quick sanity check before you paste it into Outlook.
Most readers who search for this phrase are not asking about the small grey paragraph marks Outlook paints in the editor. They are asking how to scrub the actual glyphs that have somehow ended up in their draft: a stray stylized currency symbol copied from a PDF, an arrow left behind by an automated template, a copyright glyph that looks broken on the recipient's phone, or invisible punctuation that throws line wrapping off. Outlook's own formatting-marks toggle is the wrong tool for that work because it changes what the editor shows you, not what the recipient reads.
Why Special Characters Trip Up Outlook Mail
Outlook mail is unusually sensitive to non-ASCII text for three reasons. First, the recipient's email client may not have a font that contains the character, so the system falls back to a substitute glyph that looks like a missing-symbol box. Second, plain-text and rich-text versions of the same message are stored separately, and characters that survive one path can be silently dropped or HTML-escaped in the other. Third, many users compose the message in Word, Notepad, or a web form, then paste into Outlook, which preserves whatever decoration came along with the paste. The result is an inbox full of messages that look clean on the sender's screen but arrive cluttered on the recipient's.
Stripping the underlying code points before you paste solves all three problems at once. Once the offending characters are gone from the source string, there is nothing for the recipient's font fallback to substitute, nothing for the HTML serializer to escape, and nothing for the paste buffer to drag in.
How the Tool's Two Modes Map to Outlook Use
The Special Characters Remover exposes exactly two modes, and choosing between them is the main decision the tool asks of you. Symbols-only mode removes every code point whose Unicode General_Category begins with S — currency signs, mathematical operators, arrows, geometric shapes, many emoji, and the like — while leaving punctuation (commas, periods, exclamation marks, question marks) intact. Broad mode removes the S categories plus every code point whose category begins with P, which includes ordinary punctuation, connector punctuation such as underscore, and punctuation used by non-Latin writing systems. These P and S labels are part of the Unicode General Category Values specification, not a custom blacklist.
Take the sample string Hi, $5! as a worked illustration. In symbols-only mode, the dollar sign is removed because it is a currency symbol under category Sc, while the comma and exclamation mark survive because they are punctuation, producing Hi, 5!. In broad mode, all three characters are removed, producing Hi 5. The tool does not insert replacement spaces, so two adjacent words whose only separator was a removed comma or symbol will sit flush against each other in the output; review the cleaned text for that artifact before sending.
How to Remove Special Characters Before Pasting Into Outlook Mail
- Paste the full body text — including signatures, quoted replies, and any decorative separators — into the input field of the Special Characters Remover.
- Pick the mode that matches your goal: choose Symbols only if you want commas, periods, and other punctuation preserved; choose Symbols and punctuation if you want the body reduced to letters, digits, marks, and whitespace only.
- Run the cleanup and read the removed-code-point count the tool displays next to the cleaned output; if the count is unexpectedly high, re-check the mode selection before you trust the result.
- Copy the cleaned output, paste it into the Outlook draft window, and send a test message to yourself or a colleague whose Outlook setup you trust to confirm the message renders cleanly.
- Repeat the same pass for any subject-line text, alt-text, or signature block that also contains stray symbols.
Comparing the Two Removal Modes
| Property | Symbols only | Symbols and punctuation |
|---|---|---|
| Unicode categories removed | S (currency, math, arrows, many emoji) | P and S (P covers punctuation and connector punctuation) |
| Behavior on the sample Hi, $5! | Becomes Hi, 5! | Becomes Hi 5 |
| Best Outlook mail use case | Strip stray currency, arrows, or emoji without breaking sentence flow | Reduce body to letters, digits, marks, and whitespace only |
| Letters and decimal digits | Kept exactly | Kept exactly |
| Combining marks on accented letters | Kept exactly | Kept exactly |
| Whitespace and line breaks | Preserved, not trimmed or collapsed | Preserved, not trimmed or collapsed |
| Replacement spaces inserted | None | None |
| Input cap | 1,000,000 UTF-16 code units | 1,000,000 UTF-16 code units |
What the Remover Leaves Alone on Purpose
The product contract is explicit about what the filter does not touch. Letters of any script, decimal digits, other-number code points, combining marks, separators, and whitespace are all preserved unchanged. A letter such as é written as an e followed by a combining acute accent stays a single visible character because the base letter is in category L and the combining mark is in category M, neither of which the S or P patterns match. The same is true for Greek, Cyrillic, Arabic, and CJK letters, so an international name or address inside the Outlook mail body survives a cleanup pass untouched.
The remover also refuses to guess at what a character looked like. It does not inspect the rendered glyph and decide that a particular comma is "really" a special symbol; it asks the Unicode General_Category value, which is a property of the code point rather than of the font. The matching itself is performed by the JavaScript engine's Unicode property escape syntax, as described in the ECMAScript language specification. That is why connector punctuation such as the underscore (category Pc) survives in symbols-only mode but is removed in broad mode: the tool is following the category table, not a visual judgement.
One artifact to watch for: when punctuation or a symbol sits between two words and gets removed, those words end up adjacent in the output. The tool deliberately does not insert replacement spaces because it cannot infer the intended grammar of your sentence. If the cleaned text looks like DearJohn, you know a comma or symbol that originally separated Dear from John was deleted; restore the space manually before sending.
Where This Approach Should Not Be Used
Removing characters labeled special is not the same as sanitizing data. Do not use this tool as the last line of defense for SQL fragments, HTML bodies, shell commands, URLs, filenames, usernames, or authentication data. Each of those destinations has its own grammar and its own allowlist of characters that are valid, and a strip-everything-special pass can produce output that is technically shorter but semantically wrong for the destination. The product documentation calls this out explicitly: safe validation depends on the destination's allowlist and grammar, not on deleting characters labeled special.
The result can also change what your mail says. Stripping the dollar sign from a price removes its currency, stripping an arrow can remove a directional instruction, and stripping punctuation can change how a screen reader pronounces the sentence. Review the cleaned output before you publish the message, and for subject lines that rely on a single symbol for meaning, consider rewriting the line rather than relying on the filter.
For picking a specific symbol to keep or copy, the Special Characters Copy and Paste reference lists the exact code points by official name. For cleaning stray whitespace such as double spaces pasted from a template, the Whitespace Remover is the right adjacent tool. The Outlook formatting-marks toggle inside the composer — usually bound to Ctrl+Shift+8 or the ¶ button on the Format Text ribbon — hides paragraph and tab indicators in your view of the draft but does not remove them from the message body, so it is not a substitute for a Unicode-aware strip.
