email subject is truncated if text was wrapped in the middle of a multi-byte character
1.73 KB, message/rfc822
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; hu; rv:126.96.36.199) Gecko/20071127 Firefox/188.8.131.52 Build Identifier: version 3.0a1pre (2007121703) An email having a multi-byte encoded subject header (for example UTF-8) is displayed truncated if the subject is wrapped in the middle of a multi-byte character. Reproducible: Always Steps to Reproduce: Any Thunderbird installation, tried on Mac, Windows 2000 and Windows XP. I have checked latest nightly buid on Windows XP. An email is necessary with the following subject: Subject: =?UTF-8?Q?=C3=9Cdv=C3=B6z=C3=B6lj=C3=BCk_a_3._Budapest_Fringe_Fesztiv=C3?= =?UTF-8?Q?=A1l_jelentkez=C5=91it!?= Actual Results: Displayed subject is Üdvözöljük a 3. Budapest Fringe Fesztiv� Expected Results: Expected subject is Üdvözöljük a 3. Budapest Fringe Fesztivál jelentkezőit! Hungarian accented character 'á' is represented as C3 A1 bytes, in quoted-printable encoding this is =C3=A1. It was wrapped to two parts. Thinderbird decodes the first part, the string ends with C3, this is not a correct UTF-8 character, decoder places a '?' mark in a diamond that means an incorrect character. Thundrbird does this (causing error): 1. decodes first Q-encoded part 2. interprets the part (!) as UTF-8 3. looks for other parts and concatenates results Good way to decode this: 1. decode all Q-encoded parts first 2. concatenate them 3. interpret the whole string as UTF-8
Are you sure that subject is correctly encoded? Is it legal for the encoding to break up one character to two parts? (I can send a mail with that subject in thunderbird and receive it correctly.)
RFC 2047 clearly says; > http://www.faqs.org/rfcs/rfc2047.html > The 'encoded-text' in an 'encoded-word' must be self-contained; > 'encoded-text' MUST NOT be continued from one 'encoded-word' to another. INVALID. > X-Mailer: PHPMailer (phpmailer.sourceforge.net) [version 2.0.0 rc3] Probably bug of PHPMailer. To bug opener: Report problem to PHPMailer project please, instead of bugzilla.mozilla.org, if the mail is really generated by PHPMailer.
