Misaligned error rendering with UTF-16 symbols

What happened?

Error rendering is shifted when UTF-16 symbols are present in the code.
Almost the same issue as in #223 (comment), but in compiler itself.

Minimal reproduction steps

Compile this program:

fn main(){
    /*😀😀*/ let a: u8 = 65536;
}

and error would look like this:

  |
2 |     /*😀😀*/ let a: u8 = 65536;
  |                               ^^^^^ Cannot parse: number too large to fit in target type
