CSharpier Rider plugin mangles UTF-8 characters when running on save

[kaelon141]

• IDE Version: JetBrains Rider 2023.3.4
• Extension Version: 1.6.3
• CSharpier Version: 0.27.2+b456544aad8957d0e2026afe1a37544bb74552ba
• Operating System: Windows 11
• .csharpierrc Settings: printWidth: 120
• .editorconfig Settings: N/A

Log Output

Steps to reproduce

1. Ensure the csharpier plugin is installed in Rider and ensure the "Run on Save" setting is turned on in the plugin's settings.
2. Open any .cs file
3. Ensure the file encoding is set to UTF-8 with BOM
4. Type any non-ascii UTF-8 character, like ë or ä
5. Save the file.

Expected behavior
The non-ascii UTF-8 character is preserved

Actual behavior
The character is mangled. For example, ë becomes ë. Saving this again then mangles the characters again, resulting in ë.

I've narrowed this down to the CSharpier plugin in Rider, because non-ascii UTF-8 characters are preserved correctly when turning off the 'Run on Save' setting of the plugin. When running csharpier from the terminal using dotnet csharpier . --config-path ./.csharpierrc.yaml, the problem does not arise either.

I haven't been able to reproduce the problem and matched your setup exactly, except for the contents of the file.

Does this still occur with a brand new project + new file?
Can you also try it with "Use CSharpier Server" turned on to see if that makes a difference?

This is the file I used for testing with UTF-8-BOM encoding

namespace PluginIssue;

public class Class1ë
{
    private string Fieldä = "ä";
}

Hello, I have provided a reproduction here. https://github.com/OwenCross289/CsharpierRepro This issue appears to ONLY be with the Rider plugin. Running CSharpier through the CLI does NOT affect this.

Thanks for the great tool :)

If there is anything I can do to help this get fixed please let me know :)
