wp-mail.php utf8 (umlauts)

[revolution48]

Wordpress version 2.5 wp-mail.php trims post-by-email content body at german umlauts. We can fix this by adding utf8_decode to wp-mail.php

Line 154

$content = utf8_encode($content);

That's all, folks.

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

added has-patch and needs-testing flags

Milestone 2.5.2 deleted

Laenny's patch works fine if we also decode the body content. To do this add:

Line 76
$content = quoted_printable_decode($content);

Why is this moved time and time again? The Swedish community starting to get annoyed by this. Should be patched for 2.7. This is an easy one to patch!

Swedish characters for filosofo to work with

iconv isn't always available so we'll probably need some function_exists checks.

Moved to 2.8 for now.

Patch very welcome but we need to ensure we cope with all mail encodings and don't break different ones instead.

Replying to westi:

Moved to 2.8 for now.

You have to be freaking kidding med >:

Patch wp-mail.iconv.diff seems to handle the character encoding issues in my tests.

Patch looks good.

Rolling this into 2.7 :-)

(In [10011]) Improve wp-mail utf8 support. Fixes #6788 props filosofo.
