FAQ
Use NFC for general storage and display. It keeps text compact while preserving normal accented characters.
Use NFKC when you want compatibility folding, such as fullwidth letters to regular letters or circled numbers to digits.
No. It only removes combining marks after decomposition. It does not convert scripts or rewrite words phonetically.
Unicode forms can change code points without changing the rendered appearance. Check code point and UTF-8 byte changes in the result panel.
No. It can reduce some compatibility differences, but it is not a security scanner for confusables, bidi controls, or domain spoofing.
