I was having a poke around (as I'm also experiencing this), and it
seems to be an issue in:
Specifically, the VisualLocationTranslator class - it's either an
off-by-one error (which I can't immediately pick up on, because the
code is quite complex), or it needs to be made a bit more clever in
detecting when the position being looked up lies in the middle of a
character. A quick hack was to change line 1267 to this:
return new DocumentLocation (lineNumber, column - 1);
BUT, this IS NOT the correct fix - it simply disguises the issue (i.e.
gives you almost the expected behaviour) but it also introduces a bug
that stops you being able to select the last character on a line.
Clearly, if it's an off-by-one error, it's elsewhere in the class when
the column index is being calculated; but I see lots of complicated
calculations that will require further study.
Probably someone with a lot more knowledge than me about this class
should delve into it and take a look...
Hope this helps,
