I’m not sure what you mean.  This line contains two characters: ‘u’ with
umlaut followed by ‘x’.  ‘ü’ is in the first column, and ‘x’ in the
second column.

If we get a different column number, that means we’re looking at a
different line.  It could be because the encoding of the input port from
which that line was read was incorrectly specified.  This is the issue
what would need to be fixed.

Is there a simple way to reproduce the issue with LilyPond?

Thanks,
