Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The search_replace tool corrupts special characters (á, é, í, ó, ú, ñ) in Delphi .pas files encoded as ANSI/Windows-1252, even when modifying small sections of code.

Steps to Reproduce

  1. Open a Delphi .pas file with ANSI/Windows-1252 encoding containing Spanish characters
  2. Use search_replace to modify any section of the file
  3. Special characters get corrupted (e.g., ‘á’ becomes ‘á’, then ‘úscula’)

Expected Behavior

The tool should preserve the original file encoding and not corrupt existing special characters.

Actual Behavior:
Special characters are corrupted even in lines that were not directly targeted for modification, but were part of a larger context block.

Operating System

Yes - Cursor is unusable

The AI assistant's file editing tool (search_replace) cannot preserve the original encoding (GBK/GB2312) when editing files, causing Chinese characters to become garbled
