A unicode cleaner is a free online tool that fixes messy Unicode text. It converts fancy styled and fullwidth characters to plain ASCII, strips accents from letters, replaces look-alike confusable characters with their ASCII twins, and removes emoji and symbols, leaving clean text that works everywhere.
Cleaned text
How do I convert fancy Unicode text to plain text?
Short answer: Paste the styled text into the cleaner with the fancy to ASCII option enabled. The tool applies Unicode normalization, which maps mathematical bold, italic, script and fullwidth characters back to their plain equivalents. Your output is clean ASCII that pastes correctly into forms, spreadsheets, code editors and anywhere styled Unicode would break.
This fixes bios, product names and headlines copied from social apps that use styled fonts.
Why do look-alike characters cause problems?
Short answer: Characters from different scripts can be visually identical but have different code points, so exact-match search, login checks and URL comparisons fail silently. A Cyrillic а in a password or domain looks right but never matches the Latin a. Replacing confusables with ASCII twins removes this invisible mismatch before it causes real damage.
It is also a classic phishing trick: always normalize confusables in domains and usernames.
How do I remove accents from text?
Short answer: Paste your text and tick the strip diacritics option. The tool decomposes accented letters into their base letter plus a combining mark, then deletes the marks, turning café into cafe and résumé into resume. Use this for slugs, usernames and database imports; leave it off when the accents carry meaning you want to keep.
Base letters are always preserved, so nothing is lost except the accent marks.
Frequently asked questions
How do I convert fancy Unicode text to plain ASCII?
Paste the text and keep convert fancy and fullwidth to plain ASCII ticked. The tool normalizes styled mathematical letters, fullwidth forms and similar compatibility characters into their plain ASCII equivalents. Diacritics, confusables and emoji are handled by their own separate options.
What does strip diacritics do?
It removes accent marks from letters while keeping the base letter, so café becomes cafe, naïve becomes naive and Zürich becomes Zurich. This is useful for URLs, usernames, database fields and systems that only accept plain ASCII. Tick the option only when you want accents gone; otherwise they are preserved.
What are Unicode confusables?
Confusables are characters from different scripts that look identical, like the Cyrillic а and the Latin a. They cause spoofed URLs, failed logins and broken searches. The replace look-alikes option swaps common Cyrillic and Greek look-alikes for their ASCII twins, removing a sneaky source of bugs.
Can I remove emoji from text?
Yes. Tick remove emoji and symbols to delete pictographs, emoji modifiers and decorative symbols while keeping letters, numbers and punctuation. For maximum strictness, use keep only ASCII instead, which drops every character outside the basic ASCII range.
Will it damage text in other languages?
Only if you ask it to. The options are independent: leave strip diacritics and keep only ASCII off, and accented or non-Latin text passes through untouched. Conversion only changes the character classes you select.
