RTF transcript export with AI-generated content produces corrupted characters Description: When exporting a transcript as RTF from the Mac desktop app, any AI-generated content (for example, from Add Chapters) that includes smart punctuation results in corrupted characters in standard editors. Steps to Reproduce: 1. Open Descript (Mac desktop). 2. Generate or edit a transcript using an AI tool (e.g., Add Chapters). 3. Export transcript → RTF. 4. Open the exported RTF in macOS TextEdit or Microsoft Word. Expected Result: All punctuation (curly quotes, non-breaking hyphens, en/em dashes) displays correctly. Actual Result: Unicode typography characters appear as garbled text (mojibake), for example: • Curly single quote (‘) → ‘ • Curly single quote (’) → ’ • Non-breaking hyphen (‑) → ‑ ASCII characters (straight quotes, standard hyphens) display correctly. Additional Notes: • Exporting the same transcript as Markdown (.md) or DOCX does not reproduce this issue, indicating a problem in the RTF export encoding or Unicode handling in Descript. • This occurs immediately upon opening the RTF; no copying or pasting is involved. Environment: • Descript Mac desktop app (latest version) • macOS [insert version] • Test editors: TextEdit, Microsoft Word Impact: Breaks transcripts that contain AI-generated content and forces manual encoding fixes, making RTF export unreliable for workflows that require Unicode-safe punctuation.
