I can see Pd accepts characters in different alphabets,. If I change my macos settings to have an input in arabic or something, it's fine in Pd comments and stuff.

I can switch back and forth between different alphabets and Pd just works fine with it. Of course this is useful for labels and comments and stuff

Anyway, the same doesn't work for cyclone/comment and I wonder where in Pd's code it takes care of that, so I could do the same automatica detection for cyclone/comment

any hints where I should look?

thanks!
