Non-ASCII characters get replaced with '?' in changeset metadata

[anonymous]

With TracMercurial, non-ASCII characters in changeset metadata strings get replaced with question marks. The plugin should set os.environ['HGENCODING'] = 'utf-8'.

I think in actuality this behavior can vary depending on the locale that Trac is running with, but I think it should just use UTF-8 regardless, since the plugin seems to expect that anyway (with calls to to_unicode(), which tries to decode from UTF-8 by default).

I'm not sure where exactly in the code it should set this, but this works for me, at least:

     # The new `demandimport` mechanism doesn't play well with code relying
     # on the `ImportError` exception being caught.

I can second that, expecially when using mod_wsgi I got that problem. Using the fix described inside my trac.wsgi file eliminates the problem.

With standalone tracd that problem never arised.

I'm using hg (serv) too via mod_wsgi and there I didn't had to setup that variable. Might be something inside hg.
