Character Encoding Handling Fails for WINDOWS-1252 ADVPL Files

I have the same problem, with Delphi ANSI .pas files

Same problem with php files in latin1.
It seems that Claude Code can only open file sin UTF-8. It would be great that it respect the charset of the files.

I have the same problem with Delphi too.

Same problem here, even when I instruct Claude to use Windows-1252 encoding trough CLAUDE.md

While Code Claude does not have a native alternative, I created a CLI in GO that edits files respecting the file format, and I made this instruction from CLAUDE.md

I'm facing the same issue with Windows-1252 encoding being modified by Claude to UTF-8.

While Code Claude does not have a native alternative, I created a CLI in GO that edits files respecting the file format, and I made this instruction from CLAUDE.md

Can you please provide more informations ?

Perhaps is it possible to manage this issue with a MCP ?

It’s a command-line tool (CLI) where I specify the file name and the encoding type. By default, it automatically reads and writes the content.
In the CLAUDE.md file, I explain that any file creation or editing should use this tool, and I describe its parameters there.
When editing occurs, Claude uses this CLI tool.
The issue is that Claude Code uses UTF-8 by default, but not all files are encoded that way — and the problem lies in its native editing tool.

If people are interested, I can release the code as open source, since to me, this would be an easy fix that Anthropic could have implemented natively.

If you could share the script, I would appreciate it

I've managed to fix this by modifiyng %APPDATA%\npm\node_modules\@anthropic-ai\claude-code\cli.js and changing the default encoding to latin1.
There is a function which determines the file encoding by inspecting the BOM and falls back to utf8.
Search for utf16le and replace the fallback return values to latin1:

Great !
Could you please add, inside the Installation section of the README.md, what you've wrote in the CLAUDE.md ?
Because I'm not really sure what to tell him '^^
Thanks in advance :)

CLAUDE.md example.
In this example, I added cctools to the Windows environment variable.
If it’s copied to a project, you’ll need to change ./cctools.

Thanks you @devslimbr it works fine for me.

It's much easier for Claude AI to solve this than to keep doing hacks.
