Mojibuster

Fix broken characters in subtitles

Your player shows é or � instead of é? Drop the SRT or VTT file into the box – Mojibuster saves it as clean UTF-8.

Works with text and these files:

  • CSV
  • TXT
  • JSON
  • XML
  • SRT
  • VTT
  • TSV
  • MD
  • HTML
  • SQL
  • LOG

For example Excel exports, database dumps, subtitles or website code.

Why subtitles show broken characters

SRT files don’t declare their character encoding. Many older subtitles are saved in Windows-1252, but modern players and smart TVs expect UTF-8 – accented letters then appear as �. And if a player reads a UTF-8 file as Windows-1252, it shows é instead of é.

How to repair SRT and VTT files

  1. Drag the subtitle file into the box above.
  2. Mojibuster detects the encoding and repairs broken characters.
  3. Download the file and use it to replace the old one next to your video.

Timestamps, numbering and formatting stay unchanged.

Tips for players

  • VLC: Under “Tools → Preferences → Subtitles/OSD” you can set the default encoding.
  • Smart TVs and streaming apps almost always expect UTF-8 – so save subtitles as UTF-8 without a BOM.
  • WebVTT files (.vtt) must always be UTF-8 according to the standard.

Frequently asked questions

Do the timestamps stay the same?

Yes. Mojibuster only changes broken characters – timestamps, line numbers and blank lines stay exactly as they were.

Can I repair several subtitle files at once?

For now it’s one file after another. Each file is done in seconds.

My player still shows errors after the repair – what now?

Check whether a fixed encoding is set in the player and switch it to UTF-8 or “Auto”.
