Because my sister and a friend wanted to blog in Dutch, I've written locale handling for pyblosxom.
It's disabled by default, but once it's enabled, "date-style" URL's (http://your.blog/2006/May) will only work in the set locale (http://your.blog/2006/mei if your locale is Dutch, for example). It takes care not to break "standard" time/date formats (W3C, RFC2822), too. Most plugins I've tried also work with it out of the box.
If a plugin doesn't work, please report it to me, so I can send the author a patch. Usually it's an easy fix (don't use static names for months, etc.).
I've upgraded to PyBlosxom 1.3. There shouldn't be any breakage (the RSS 2.0 feed changed a bit, but that shouldn't be a problem). I need to migrate to the new flavour system though.. it looks nice.
