For instance when asking for code actions on caféx, I get no suggestions and see this in the lsp logs

I assume it’s because codebook does not handle multi-byte chars. The panic actually occurs within spellbook but I’m not sure whether the error is within spellbook or if it’s due to the way codebook uses it. I see multi-byte chars in spellbook tests, which could indicate the issue is in codebook
