In LSP, a position is represented as a line number and a column offset (in Unicode code units): https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#position This is pretty elegant. You'll get the correct line regardless of encoding bugs, and the editor already knows the line number so it's cheap to compute.

I'm experimenting with diagnostics formatting. * I've added a left margin, showing both the file name and line numbers * I'm showing one line of context above/below the offending line. * I'm using grey for comments. What do you think? Is there anything you'd change?

Further tinkering with diagnostics, following feedback! * Two lines of context above and below now. * The caret is included in the line below where possible. * Syntax highlighting of keywords. I kinda feel that smart context sizing would be better. What do you think so far?
