However, I have the same issue on my Mac

Description

I was going to use vscode's ruby-lsp plugin. However, after struggling for a while, I could not make the definition jump.
The cause seems to be the presence of Japanese comments in the file.

In the attached Ruby code, I assume a situation like jumping from pp TEST to TEST = 'test'.' In the case of the code written in success file 1', it succeeds. But for the code in failed file, it fails. The only difference is that the Japanese comment # テスト` is on the line above the jump source.

Furthermore, if you look at success file 2, it succeeds if the same Japanese comment is added to the line below the jump source.

If there is any information I am missing, please let me know.

Expected output

Maybe this is true for other languages as well. I hope that eventually Japanese will be handled properly and we can jump from pp TEST to TEST = 'test' in examples like failed file.

Thank you for the bug report!

I suspect this is related to #1251. The Prism parser returns byte instead of character locations, so multibyte characters are currently throwing off the language server. We need to come up with a strategy to fix this generally for the entire language server since locations are used everywhere.

Thanks for getting back to me. I could not find that Issue. Sorry to have bothered you.

It seems like a difficult issue to solve. I will wait patiently.
I look forward to having a great product available again. I wish you the best of luck!
