Feature Item4074 "TOC and heading anchors not multi-byte aware" is bringing some grief to people trying to install TWiki: A newly installed TWiki fails with Apache error log entry Can't locate Unicodepath in @INC as described in TWiki:Support/SID-00291.

TWiki:Support/SID-00291 is the most viewed support topic on twiki.org! Awstats reports 480 searches a month (15/day) for this error string. I am rasing this as a release blocker for 5.0.

Proposed fix, options:

  1. Ship Unicodepath with TWiki
  2. Load this module optional
  3. Other?

-- TWiki:Main/PeterThoeny - 27 Apr 2010

Another option could be:

Add better message and suggestion on how to install this module/which module?-instead of throwing error message out. The message should be added in TWiki and in "configure" scripts - so the administrator takes care of installing dependency.

Ship Unicodepath... (which is Unicode::String) is TWiki can be bad idea-its maintenance work.

Just compared TWiki/Render.pm between trunk and 4.3 release. It turns out that The Unicode code has only be applied to the 4.3 branch, so we are good for trunk.

That means, trunk does not cut anchors properly based on Unicode chars. I am changing this from urgent to normal, and change the heading to reflect the new scope.
