Foswiki 2.0.1 crashes on TreePlugin activation

Hi everyone,

my Foswiki installation of 2.0.1 crashes on activation of TreePlugin 1.9.1

The error message is as follows:
Foswiki detected an internal error - please check your Foswiki logs and webserver logs for more information.
utf8 "\xA9" does not map to Unicode

Here's the log entry:

Version of Encode is 2.76

Any clue about what's going on?

This needs a task. With the change of Foswik internals to Unicode, any extensions that interface with the outside world will need modifications for Foswiki 2.0. With 300+ extensions we had to handle these on an as-reported basis.

See Item13483. I'll add this to the list.

Simple fix. The TreePlugin topic contains a high character which is causing the error. Otherwise it seems to work fine. It's the copyright symbol. You can get around the issue by manually editing data/System/TreePlugin.txt and removing the copyright symbol, or change it to the (c) text, or html entity &copy;
