Уверен, с KOI8 работать не будет. Непоследовательно идут буквы.
С perldoc.com, faq по regex:
How can I match a locale-smart version of /[a-zA-Z]/?  toc

One alphabetic character would be /[^\W\d_]/, no matter what locale you're
in. Non-alphabetics would be /[\W\d_]/ (assuming you don't consider an
underscore a letter).

И еще в подтверждение моей правоты - из man regex:       
A bracket expression is a list of characters enclosed in `[]'.  It nor-    
mally matches  any single character from the list (but see below).  If   
the list begins with `^', it matches  any  single  character  (but  see 
below)  not  from  the rest of the list.  If two characters in the list
are separated by `-', this is shorthand for the full range  of charac-     
ters  between  those  two  (inclusive)  in the collating sequence, e.g.    
`[0-9]' in ASCII matches any decimal digit.  It is illegal(!)  for two    
ranges  to share an endpoint, e.g. `a-c-e'. Ranges are very collating-   
sequence-dependent, and portable programs should avoid relying on them.

То есть пользуйтесь use locale; и \w, как и положено, или задавайте ранг
так: [абвгдежзийкл] :)
