[BUG] 2.0.3 change half-width space to ` ` automactially

Hi thanks for this wonderful editor, But we found version 2.0.3 automatically converts regular spaces to ` ` , while version 2.0.2 does not . ### Expected Behavior Regular spaces should remain as normal space characters in the output, maintaining consistency with version 2.0.2 behavior. According to semantic versioning, patch versions (2.0.2 → 2.0.3) should only include backwards-compatible bug fixes, not behavioral changes.
