Some japanese characters are encoded not correct
e.g   "." (dot) or "?" (question mark) are displayed,
instead of jap. char. Sometimes a wrong jap. character
is displayed as well.

We tried encoding:
-  ISO-2022-JP  (poor result)
-  ISO-2022-JP-2  (garbage are displayed)
-  Shift-JIS  (..)
-  EUC-JP  (..)
  
For test message please check: (test account for IMP 2.2.6)
   -  Host: webmail.oberon.net
   -  POP-ID: chuck@europe.jis.de
   -  POP-PW: sodiciHE
   There are japanese emails in the Inbox.

We checked with:
-  Client OS: 
   o  Windows98 German, Japanese
   o  Windows2000 Japanese
   o  FreeBSD 4.2
-  Browser: IE5.0 German, Japanese
   o  Netscape 4.75 German, Japanese

Current IMP 2.2.6 configuration:
-  Setting in *lang.php3*
   o  $lang->charset['jp'] = 'ISO-2022-JP';
   

Thanks for help
