Description of problem:  
slrn cannot display the cyrillic text. If the newsserver serves them in  
the KOI8-R encoding, the cyrillic text is not display at all (blank  
symbols appear). If the server enconding is UTF-8, the content is hardly  
readable (see screenshot): most of the symbols are replaced with question  
marks.  
 
I guess there are two problems: 
First, it seems not to convert the article to the UTF-8 character set 
(and in its config file, /etc/slrn.rc, utf-8 is not indicated as a valid 
charset value). 
Second, it seems that it incorrectly determines printable characters even 
for UTF-8 charset. 
  
Version-Release number of selected component (if applicable):  
slrn-0.9.7.4  
  
How reproducible:  
Run slrn on any USENET group with Russian posts.
