Subtitles Fixer
The most advanced repair algorithm for Romanian subtitles - not a simple find & replace, but a 5-step pipeline that understands the Romanian language.
About this project
Flawless subtitles, clean folders. No missing diacritics or disorganized files. Select the folder, preview the changes, and fix everything in a single click.
Not a simple find & replace - it is a 5-step pipeline that understands the Romanian language. A complete dictionary generated from Hunspell ro_RO with all inflected forms validates every repaired word.
Encoding detection (Win-1250, ISO-8859-2, CP852, UTF-8 BOM) uses a confidence score to automatically choose the correct encoding. Markers like ?, � are replaced with all possible combinations of ș, ț, ă, â, î and validated against the dictionary.
When the dictionary alone can't decide, bigram and trigram statistical scoring based on Romanian language patterns breaks the tie. A dedicated pass detects and repairs misplaced diacritics, and cedilla forms (ş/ţ) are automatically converted to the correct comma-below Unicode standard (ș/ț).
Zero data loss: automatic backup before any modification, one-click restore. Everything runs 100% locally on your PC - no cloud, no account, no trackers. Auto-update from GitHub Releases.
