Hello,
 
I am desperately looking for a solution of a problem that seems quite
simple.
 
I need a PHP script to create an email message in a way that a subject line
in Hebrew will be readable in all mail clients. Some mail clients cannot
cope with Hebrew if they don't have character set explicitly denoted. 
 
Is there a possibility in PHP allowing to encode a string
with WIN-1255 character set encoding? The result should look like:
 
=?windows-1255?B?Rlc6IOz26eHl+CDk8uXj6e0=?=
 
which the mail client then is able to decode back into Hebrew. 
 
If anyone has a solution for another character set, I suppose it can also
help.
 
Will be grateful for any hint or idea.
