Hi,
--- note ---
I sent a similar message already to php-i18n - but this list seems
not to be used very much (20 messages this year) so I am posting it
here again...
------------
I try to send messages written in Japanese (Kana/Kanji) with php.
Everything works fine - only when the subject (or the name of the
sender) becomes longer, there seems to be something wrong with the
encoding: Neither my nor the mail reader of other (Japanese) friends
decodes the mime string. At the place of the Japanese Characters,
the mime string itself is displayed in the subject (to, reply to)
field.
As this doesn't happen for other Japanese emails with even longer
subjects, I suppose I did something wrong ... but what?
Here how I convert the subject (the name is converted using the same
method and the sources are saved in UTF-8 using emacs):
$subjectJIS = mb_convert_encoding($subject, "ISO-2022-JP", "AUTO");
$subjectMIME = mb_encode_mimeheader($subjectJIS, "ISO-2022-JP", "B");
...snip...
mail($to, $subjectMIME, $bodyJIS, $headers);
Here part of the message as it is displayed by my mail program:

If anybody can explain me the problem I would be most grateful :)
Thanks, Dietrich

PS: I appended a little example program which produces the problem.
The same program works correctly when using the following values:
$subject = "かな漢字";
$senderName = "かな漢字";
Thanks for your help :)
