Thanks for trying to help but this is more complicated than I thought and I don't have the patience for a deep dive right now :) Unicode is complicated under the hood but we should have some libraries to help right? I mean the user thinks of these things as "characters" be it "A" or the unicode symbol 👍 so we should be able to operate on that basis as well. Something like an iterator that return the character (wide char) and byte offset or writing would be a nice place to start. I have a parser/tokenizer I want to update so I'm trying to find tokens by advancing one character at a time. That's why I have a requirement to know which character is next in the file and probably the byte offset also so it can be referenced later.
