problems with helma.Mail and german Umlaute

Hi

when sending emails containing german Umlaute in it's subject or body  
these characters get garbled - the solution I found is this (I know  
hardcoding isn't a good idea, but I just used this for testing):

change line 325 to:
message.setSubject(subject.toString(), "ISO-8859-15");
change line 136 to:
message.setText(buffer.toString(), "ISO-8859-15");

perhaps these problems are related to the fact that I'm using a Mac  
or that all my systems use en_US as default locale
