[TYPO3-dev] quoted-printable encoded email subject

[Ivan Kartolo]

Hi devs,

before I'm posting a bug and a patch in bugtracker, I want to have some
of your comments.

Based on RFC 1342 [1], a quoted-printable encoded email subject must
have the following structure:

"=" "?" charset "?" encoding "?" encoded-text "?" "="

The encodeHeader function in t3lib_div (and quoted_printable function)
does this really good. Until if the last character of the encoded-text
is a question mark ("?"). (thanks to Michiel Roos for reporting this [2]).

The question is, what if question mark ("?") is also found in the middle
of encoded-text? I think it's also not complied the RFC 1342.

here are some solutions, which I can think of:
1. patch direct_mail, which search for question mark in the subject and
encode these before sending them to encodeHeader function.
2. patch quoted_printable function, so that ASCII 63 ("?") will also be
encoded.

I would like to hear your comments, since I'm not sure whether question
mark is prohibited in quoted_printable encoded text...
