Problem parsing Attachment Filename

[obwandner@…]

After Fetching a Mail, with email2trac we have sometimes following Problem with the filename of the attachments:

=?iso-8859-1?Q?Erl=E4uterung=2Epdf?= should by named as Erläuterung.pdf

Mail send by MS-Outlook of Exchange to postfix the fetch by fetchmail email2trac on a Debian Machine.

I just tried it to send an email with special chars in it, but that is encoded UTF and then trac has no problems with it. Can you send an email to basv@… that has an attachment with this enconding.

Did it work previously? (an earlier version of email2trac)

I don't now, we use the script since 2010-02-01, I have it downloaded 3 Days before.

Ok can send me a private email with this attachmnet that is encoded iso-8859? I will try to reproduce it. Trac can only handle utf-8 encoding.

There is something new happend: [attachment:"=?utf-?B?Vm9ybGFnZV9HZXNwcsOkY2hzZG9rdW1lbnRhdGlvbi5w?= =?utf-8?B?ZGY=?="]

The Filename was Coded in UTF-8 and converted to 7Bit by Outlook, then the File was Added, but the File name was also not encoded.

I am now a week off. But i think i removed to many code from the attachment() function. See r296 (revision 296). I remove the following block that causes problem you described:

1229	 	                        if sys.version_info[0] > 2 or (sys.version_info[0] == 2 and sys.version_info[1] >= 3): 
1230	 	                                try: 
1231	 	                                        filename = unicodedata.normalize('NFC', unicode(filename, 'utf-8')).encode('utf-8')   
1232	 	                                except TypeError: 
1233	 	                                        pass

(In [317]) email2trac.py.in:

• A filename name can also containt unicode chars, so convert a filename name to unicode, see #177

Did had a chance to test it?
