Korean characters broken (question marks appear between characters)

[dowon060204]

Describe the bug

When generating subtitles in Korean, characters are corrupted and appear as question marks between or instead of characters.

Example

Instead of:
풀어 이걸 죽일 수 있습니다

It shows:
풀��이��을 죽일 수 있습니다

(Question marks or broken characters appear in the Korean text)

1. Generate subtitles in Korean
2. Korean text appears as question marks in the plugin preview
3. The same issue appears in DaVinci Resolve
4. The downloaded SRT file also shows Korean text as question marks

Expected behavior

Korean text should display correctly without broken characters.

Environment

• OS: Windows
• Auto-subs version: v3.0.8
• AMD Ryzen 7 8700F 8-Core Processor \ NVIDIA GeForce RTX 5070

Additional context

This seems like an encoding issue (possibly UTF-8 not applied correctly).
Opening the SRT file in a text editor also shows corrupted characters.
