What it helps with
- Check text before sending Japanese email campaigns
- Review text before pasting into Japanese forms
- Find characters that may cause mojibake before document submission
- Review common characters such as ①, ②, ㈱, ㈲, 髙, 﨑, Ⅰ, Ⅱ, ㍉, and ㌔
How to use

- Review common characters such as ①, ②, ㈱, ㈲, 髙, 﨑, Ⅰ, Ⅱ, ㍉, and ㌔.
- Review detected positions, character types, and replacement suggestions. Suggestions still need context.

Good to know
- Detects a practical set of common characters, not every Unicode compatibility character.
- Replacement suggestions are context-dependent and should be reviewed.
- This tool does not guarantee that a target system will accept the text.
FAQ
- Does this detect every risky Unicode character?
- No. It focuses on a practical set of common Japanese compatibility and environment-dependent characters.
- Are replacements always correct?
- No. They are suggestions, and names, company names, or official documents may require a specific character.
- Does this upload text?
- No. Character checking runs in your browser and input is not sent to a server.
