#362 Problems to attach files with German umlauts to a mail

[Tim Gerundt]

I tried today to add attachments with German umlauts (äöü) to a mail. I can add them, but the umlauts get lost.

Is this a NOCC or a webserver problem?

I can reproduce this behaviour, as far as I can see in the source code it looks like a NOCC problem.

[Tim Gerundt]

One of the problems is, that NOCC not correctly encode the filename from a attachment.

If I send a file with the (funny) name "Ümlaute.txt" with Thunderbird, I got the following source code:

Content-Type: text/plain;
name="=?ISO-8859-15?Q?=DCmlaute=2Etxt?="
Content-Transfer-Encoding: base64
Content-Disposition: inline;
filename*=ISO-8859-15''%DC%6D%6C%61%75%74%65%2E%74%78%74

With NOCC is looks like the following lines:

Content-Type: text/plain;
name="Ümlaute.txt"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="Ümlaute.txt"

To show the attachment links in a mail, we use the function "link_att()". In this function we use nocc_imap::mime_header_decode() to decode the filename. Unfortantly this broke the string, if it is not decode...

use imap_utf8() in link_att() function

[Tim Gerundt]

We can fix one of the problems, if use "nocc_imap::utf8()" instead "nocc_imap::mime_header_decode()" in the link_att() function.

[Tim Gerundt]

use imap_utf8() in html/send.php

[Tim Gerundt]

A other problem is "nocc_imap::mime_header_decode()" in the html/send.php file. If we use here also "nocc_imap::utf8()" we have no problem. I'am not sure, if we really a convert function at this place, but it also not hurt. ;)

Confirmed and in work...
