From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; N; PPC; en-US; 0.8) Gecko/20010215 BuildID: 2001021502 A MIME encoded (ISO-8859-1) Subject as sent out by Eudora is not decoded by Mozilla. This was no problem in Netscape 4.7x. Even if both 4.7x and Mozilla themselves encode only the single non-ascii strings instead of the whole subject line. Reproducible: Always Steps to Reproduce: You must fetch a mail sent out by Eudora with a subject containg MIME encoded non-ASCII letters, e.g. Norwegian å (å). Actual Results: After fetching such a message you will see that the subject has not become decoded at all. So the subject will look exactly like the code. Expected Results: Normal decoding. No code display in the subjet. I don't know the RFC but Eudora is a major player in this game. Also other mailers encode messages the same way (e.g. Magellan and Nisus Email,both Mac mailers.) *Sample of how Eudora [3.1 for Mac] encode such a line: 'Subject: Re: =?ISO-8859-1?Q?Er du g=E5tt i dekning??=' Note that *the whole* subject content is included in the MIME enc. Whereas Mozilla and Netscape4.7 would encode the each non-ASCII string/letter *inside* the subject content, like in this Mozilla 0.8 sample: 'Subject: Re: Er du =?ISO-8859-1?Q?g=E5tt?= i dekning?'

I can confirm that this line doesn't decode: Subject: Re: =?ISO-8859-1?Q?Er du g=E5tt i dekning??= Working (displaying properly) is: Subject: =?iso-8859-1?Q?H=E4pp_igen_(NT)?= Subject: Re: Er du =?ISO-8859-1?Q?g=E5tt?= i dekning? Subject: Re: =?ISO-8859-1?Q?Er_du_g=E5tt_i_dekning??= The culprit seems to be the spaces inside the quoted printable text. Maybe they are disallowed by the standard, but we could be helpful anyway if the text decodes with that relaxation of the rules. Then I don't now the rules for QP coding MIME headers, so maybe we got a bug. I tested with a newer Eudora (version 4.3) on Windows and it doesn't code including the spaces. That's the first of the three "working" subjects above.
Fix checked in.
sending leak/opt bugs over to my other bugzilla account
Using build 20020322 on winxp and 20020318 on mac and linux I sent myself a message uisng Eudora 5.1 with non-ascii characters in the subject. this is displayed when reading the source Subject: =?iso-8859-1?Q?=C7=FC=EF=E9=E2=E4=E0=E5=E7=EA=EB=E8=EF?= but displays as correctly in the message pane subject field as Subject: Ηόοιβδΰεηκλθο Verified.
