Hey, thanks for the report. I can see the screenshot with a warning about an encoding mismatch between UTF-8 and Central European.
This is a known encoding issue when using AI to edit files. We have a few similar reports. Usually files get converted to UTF-8, but in your case it somehow changes from UTF-8 to Central European. The team is aware of the encoding issue and is working on a fix.
To link your report to the existing ticket, we need a bit more info:
- Does this happen every time in Plan mode, or only sometimes?
- What extensions are installed? (Settings > Extensions)
- Are your Windows regional settings set to English, or Russian, or another Central European language?
- Can you try reproducing this with a simple new C# file saved as UTF-8?
For now, the workaround is to manually re-save the file as UTF-8 after editing: bottom right corner of the editor → click the encoding → “Save with Encoding” → UTF-8.
