- Why is unicode an issue? The editor should use UTF-8. I don't think its forced to follow the Windows standard if they have their own font rendering? - Filenames is an issue, but it shouldn't be too hard to pull in a path library to do most of that for you. Which is why you should code for Windows from the start because you will quickly realize, oh yeah, maybe I couldn't hardcode forward slashes everywhere because it's going to be a pain to refactor later. And oh yeah, maybe case-insensitivity is a thing that exists. - Text encoding..? Just don't do that. Encode it the same way. Every modern editor, including Notepad, can handle \n instead of \r\n now. You needn't be re-encoding code that was pulled down from Git or whatever. - Also don't see why UUIDs are relevant - Limit on open files is probably a legit issue. But can be worked around of course. Anyway, none of these sound like major hurdles. I think the bigger hurdles are going to be low-level APIs that Rust probably doesn't have nice wrappers for. File change notifications and... I don't know what. Managing windows. Drivers.
