Why filenames turn into weird characters
ZIP archives created on Windows store filenames in legacy encodings — Shift-JIS for Japanese, GBK or Big5 for Chinese, EUC-KR for Korean. macOS assumes UTF-8, so Archive Utility renders the names as mojibake: corrupted strings of accented letters and symbols.
A second, Mac-specific problem: macOS stores Korean in decomposed Unicode (NFD), while Windows uses NFC. Copy a file across and the Korean letters split into separate jamo pieces.
Mojifix handles both. It detects which encoding produced the damage and reverses it — showing you a full before → after preview before a single file is renamed.

FAQ
How do I fix garbled filenames after unzipping on a Mac?
Drop the ZIP directly onto Mojifix. It detects the legacy encoding the archive used (Shift-JIS, GBK, Big5 or EUC-KR) and produces a repaired copy with the original filenames — you never need to know which encoding went wrong.
Why do ZIP filenames look corrupted after unzipping on macOS?
Most Windows ZIP tools store filenames in a regional legacy encoding instead of UTF-8. macOS Archive Utility decodes them as UTF-8, producing mojibake. The file contents are fine — only the names are mis-decoded.
Can it fix weird characters in existing file and folder names?
Yes. Besides ZIPs, you can drag in already-extracted files or folders and batch-rename them back to their original names.
Does my data leave my Mac?
No. Mojifix has no network access at all. Detection and repair run entirely on-device; nothing is uploaded, collected or tracked.
Is it a subscription?
No — pay once ($4.99), own it. No subscription and no in-app purchases.
