Thanks for the info!
I've implemented the iconv_mime_encode function in the Mail_Mime package as 
you can see at 
http://cvs.php.net/viewcvs.cgi/pear/Mail_Mime/mime.php?annotate=1.56#l791
In that function, I only call the replacing function if the line to encode 
contains characters that should be encoded. This is currently done with a 
regexp but I fear it might not always find all the characters.
The regexp I'm using searches for [\x80-\xFF]. This would catch any cyrilic, 
or otherwise, xtened single byte characters in charsets such as ISO-8859-XX. 
Would this work in etecting all multibte charaters, or do you know a better 
way to determine whether or not to encode a line ?

Thanks again,
Cipri
