• Convert Latin script to Cyrillic
• Translate Croatian vocabulary to Serbian

Scripts

1. Latin to Cyrillic Converter (convert_to_cyrillic.py)

Converts Serbian Latin subtitles to Cyrillic script.

• Supports Serbian Latin characters (Č, Ć, Ž, Š, Đ)
• Auto-detects file encoding
• Maintains folder structure

Usage:

# Place .srt files in the original/ folder, then run:
python convert_to_cyrillic.py

Converted files appear in the cyrillic/ folder.

2. Croatian to Serbian Translator (translate_croatian_to_serbian.py)

Translates Croatian vocabulary to Serbian equivalents in subtitle files.

Features:

• 1200+ word mappings covering:
  • Location/time adverbs (ovdje→ovde, uvijek→uvek, gdje→gde)
  • Verb conjugations (vidjeti→videti, osjećati→osećati)
  • Future tense patterns (bit ću→biću, Voljet će→Voleće)

  • Days/months (ponedjeljak→ponedeljak, siječanj→januar)
  • Vocabulary (tisuća→hiljada, vlak→voz, glazba→muzika)
• Auto-detects file encoding (UTF-8, CP1250, ISO-8859-2)
• Word boundary matching to avoid partial replacements

Usage:

# Translate a single file (creates file_sr.srt)
python translate_croatian_to_serbian.py subtitle.srt

# Translate text directly
python translate_croatian_to_serbian.py -t "Što radiš?"

# Translate all .srt files in a directory
python translate_croatian_to_serbian.py -r input_folder/
