My bibtex file is exported from zotero and has an emoji in its keywords. Removing it seems to help....

[clason]

I'm not sure if this is related, but it might be: I've been getting consistent and frequent crashes of the texlab server with Neovim since the recent crate refactor (just after 5.11.0); I believe they are related to entering non-ASCII characters.

Typical errors that show up in my log are of the form

[ERROR][2023-11-15 15:07:53] .../vim/lsp/rpc.lua:675	"rpc"	"/Users/clason/.local/share/nvim/lsp/texlab"	"stderr"	"thread 'main' panicked at /rustc/cc66ad468955717ab92600c770da8c1601a4ff33/library/alloc/src/string.rs:1766:29:\nassertion failed: self.is_char_boundary(n)\nnote: run with `RUST_BACKTRACE=1` environment variable to display a backtrace\n"

I'll investigate more.

@clason It seems to be caused by switching to the latest version of the LineIndex struct instead of vendoring line-index like we used to do before it was available on crates.io.

This commit should be the culprit: https://github.com/latex-lsp/texlab/commit/99ed167dd4b08c8ac151f01cf9bc3f4443605812

[clason]

Yes, that is consistent with my bisecting tests.

@leoleoasd Do you have a reproducing example that you can share? The LineIndex and this crash are two different problems.
