Quick Answer

Mojibake Fixer: latin1/GBK/UTF-8 fix, hex decode. Mojibake Fixer uses standard developer formulas to compute accurate results instantly.

Input text

ä½ å¥½ï¼Œä¸–ç•Œ
Could not recover (not a latin1 misdecode)

How it works

  1. 11. Take each char code as one byte (latin1 round-trip)
  2. 22. Decode those bytes as UTF-8
  3. 33. Invalid UTF-8 sequence — the corruption is of another kind (e.g. GBK misread)

Root cause of mojibake: bytes were written with one encoding but read with another. UTF-8 misread as latin1 (ä½ å¥½) is reversible — the fix mode above reverses it. UTF-8 misread as GBK (浣犲ソ) corrupts byte boundaries and is often NOT losslessly reversible. Golden rule: declare UTF-8 everywhere (meta charset, HTTP header, DB collation).
