Reproduction steps
- Start the Ruby LSP in neovim
- Open a Ruby file
- Input some string with non-ascii characters (type them one by one, the issue does not immediatly happen on copy-paste, or interact in some other way
- The Ruby LSP starts panicking, throwing seemingly random errors and warning (looks like it is misinterpreting or skipping some characters)
Code snippet or error message
By typing the following:
def test
["test", "test", "tést"]
endI get these error messages:
unexpected local variable or method; expected a `,` separator for the array elements
unexpected end-of-input, assuming it is closing the parent top level context
unexpected end-of-input; expected a `]` to close the array
