With site language set to ru and site charset utf-8 TWiki encodes subject lines in email messages like this:

Subject: [Twiki] =?iso-8859-1?q?TWiki_-_=D0=A0=D0=B5=D0=B3=D0=B8=D1=81=D1?=
   =?iso-8859-1?q?=82=D1=80=D0=B0=D1=86=D0=B8=D1=8F_=D0=B4=D0=BB=D1?=
   =?iso-8859-1?q?=8F_TWikiUser_=28user=40my=2Esite=29?=

(this example is taken from registration notification email).

The text is quoted-printable encoded UTF-8, but MIME encoding is declared to be iso-8859-1.

This is a generic TWiki problem, not specific to MailerContrib I believe.

I applied the patch attached to bug item 3969 and use the following settings in LocalSite.cfg:

  • $TWiki::cfg{Site}{Locale} = 'zh_TW.utf8';
  • $TWiki::cfg{Site}{CharSet} = 'utf-8';
  • $TWiki::cfg{Site}{Lang} = 'zh';
  • $TWiki::cfg{Site}{FullLang} = 'zh-tw';

While the email body is in utf-8 and correctly displayed, the headers are not. They are not even quoted-printable in my system. I haven't spent time looking into the problem but it should be solved before next major release.

I attached a patch that fix the encoding of the "From: " and "Subject: " line in UTF-8 environment. It include puts quotation marks `"' to senders (e.g., "TWiki Administrator").

TWiki doesn't support Unicode properly so I'm not too surprised, but this sort of thing does need fixing.

Thanks for the patch, which of course is very UTF8-specific - we really need full TWiki:Codev.UnicodeSupport, as there are more and more areas where we need UTF-8 or simply need the power of Unicode to fix I18N issues.

Fixed in unicode core.
