Problem
Caption files use the wrong encoding and display accented or non-Latin characters as replacement symbols.
Solution
Root Cause / Diagnostic:
Exporting subtitle text using ANSI, Windows-1252, or ISO-8859-1 encodings corrupts multi-byte UTF characters during platform parsing. Streaming platforms and web browsers require universal UTF-8 character encoding to map international diacritics and non-Latin alphabets correctly.
Actionable Fix:
1. Set the text export character encoding explicitly to UTF-8 without BOM (Byte Order Mark) across your NLE and subtitling software.
2. Batch-convert legacy subtitle text assets using an automated script or text editor (e.g., VS Code or Notepad++) set strictly to UTF-8.
3. Open the exported SRT/VTT file in a web browser or subtitle validator to confirm accented vowels (é, ü, ñ) and symbols render without mojibake errors.
Pro Tip:
Enforcing UTF-8 encoding across your post-production data pipeline eliminates 99% of web-based character rendering anomalies across YouTube, Facebook, and OTT players.
