wp-mail.php utf8 (umlauts)

Problem: Wordpress version 2.5 wp-mail.php cuts off subjects and content containing german umlauts.

Solution: We can fix this by adding utf8_decode to wp-mail.php

Add this code:

Line 65 $subject = utf8_encode($subject);

Line 154 $content = utf8_encode($content);

A more general solution would be nicer, this one only works for ISO-8859-1 to UTF-8 conversion. Most German Email programs use ISO-8859-1 by default, but since Wordpress does not have only have German users... You proposed patch would break if UTF-8 encoding was used, for example. I will try to find a nice, general solution using the iconv-Library.

For the subject I have done it by now:

Line 64:

old:

$subject = wp_iso_descrambler($subject);

new:

$subject = iconv_mime_decode($subject,2,'utf8');

(why reinvent the wheel?) - works like a charm with utf8 AND ISO-8859-1 subjects.

I will come back later and try to present a solution for the email body.

Patch using iconv to convert most encodings to utf8
