Hat off to you, Sir! It is worth more than pizza ...

Multibyte basically works (ru_RU.UTF-8, Mandrake^H^H^Hiva cooker, gcc 4.0.1, 
glibc 2.3.5). I.e. basic line editing (movement char, word, emacs or vi 
mode). Completion - i.e. listing etc.

Some random problems.

1. attempt to use a-a-m-c results in

apparently it correctly inserts first match but crashes at recursive 
completion attempt.


2. Attempt to complete anything beyond U'd183' results in

{pts/2}% ll уBUG: substring ends in the middle of a metachar in 
ztrsub()mpleting `files'
         ll у
{pts/2}% echo у | xxd
0000000: d183 0a                                  ...

I do not know what is magic about it; all characters before are completed 
normally. Probably it somehow clashes with META characters. The above is in 
UTF-8, it is 0400 unicode plane, character in question is 0443.

3. emacs ^W sometimes removes too much not just a previous word in Russian 
(where word delimiter in this case is space):

{pts/2}% ll    АААААА ББББББББ ВВВВВВВВВ^W
{pts/2}% 

4. Undo (in emacs or vi) often puts cursor not at previous position but at 
some random position. In the above example, if I have anyhing after cursor:

{pts/2}% ll А Б В^W
                 ^cursor here
{pts/2}% ^_
         ^ cursor here
{pts/2}% ll А Б В
            ^ cursor here

the position is really random, sometimes it is end of buffer sometimes more.

But yes, I think it makes sense enable UNICODE by default now. It seems to be 
usable, at least for simple filename completion.

Thank you
