Hi Lukáš,

first of all thanks for looking at the issue. Waldo, thanks too.

To my knowledge (correct me if I'm wrong) neither Aspel < 0.60 nor Ispell
supports utf8 spellchecking, they treat input/output in 8-bit encoding. That's
why, actually, I was surprised to see UTF-8 in a list of encodings of control
center. One could argue that it is possible to pass --encoding=utf8 to
Aspell-0.50, but from the documentation of Aspell-0.50 [1] 
<quote>
encoding 
(string) The encoding the input text is in. Valid values are ``utf-8'', 
``iso8859-*'', ``koi8-r'', ``viscii'', ``cp1252'', ``machine unsigned 16'', 
``machine unsigned 32''. However, the aspell utility will currently only 
function correctly with 8-bit encodings. I hope to provide utf-8 support in 
the future.

What spellchecker are you using? If Ispell, are you sure it is not a wrapper
around Aspell (some distros dropped Ispell)? If you do not have Aspell-0.60,
how do you spellcheck utf8 texts (like you said Aspell-0.50 cannot do that)?

Thanks for patch, I'll definitely try it once at home. However, I doubt it
solves the problem. Currently, the spellchecking i.e., pass a word to Aspell
and get suggestions, is working very well. No way to blame backend.
The problem, IMHO, is in what happens with suggested word. Namely,
there is a variable called posinline, from how I understand the code it gives
the position of a word being checked in a string. Later, lastpos is
calculated to figure out which word to replace/highlight. The part of a code
which I commented out does crazy things resulting in wrong posinline.
Did anybody understand what I said? It seems it is not clear even to
myself. :-)

PS. I faked a reply cutting&pasting from the archive, since I was not in the
