Hallo Kees!   
      
    KvE> It looks good in Thunderbird, but it will probably get mangled   
    KvE> on the way back. ;((   
      
   It looks perfect here.  I'll repost the parts that matter from a utf8 dump of   
   3 lines from your reply "MSGID: 2:280/5003.4 5b200566";   
      
   -={ ':read dump.utf8' starts }=-   
    MK> in my pants", "Jag har ekorrar i mina byxor", "У меня в   
   штанах белка",   
    MK> "Έχω σκίουροι στο παντελόνι μου" and "Ich habe   
   Eichhörnchen in meiner   
    MK> Hose", within a single message which covers five languages thus vastly   
   -={ ':read dump.utf8' ends }=-   
      
   Note that is an exact replication from your reply (ie zero jiggery-pokery).  I   
   notice that Thunderbird does a perfect wordwrap given that it obviously counts   
   multibyte characters the same as 7-bit ascii characters.  Other web based apps   
   I've seen don't as they count characters as bytes.  Kudoes to your   
   implimentation.  :-)   
      
   Does the "CHRS: UTF-8 4" kludge make any difference at all?  If so I'll turn   
   it on here but just so you know it is a total waste of bytes at this end since   
   utf-8 characters work 100% at this end without any interference or help   
   required.   
      
   Het leven is goed,
