I recently received some code to translate certain non-ascii codes in your article titles into a more URL-friendly permalink. Though, at David Black’s suggestion, I decided to use Iconv instead. Seeing that I’m creating permalinks in several projects now, I’ve extracted this into a new rails plugin: permalink_fu.
Let me know how this works out. Hopefully iconv is available on your platform too. It’s my understanding that it’s in the ruby standard library, and included with the Ruby One-Click Installer for Windows users.

Cool ! Since I’m a big fan of pretty permalinks I do appreciate this ;)
Has that code edit already made it’s way into Mephisto? We just ran into this problem last week, it would be a very timely fix :)
The plugin strip accented characters so my permalinks are awful (I’m french. I’ve lot of words with accented characters ^^). Is it possible to replace accented characters by the same character without accent ? It would be great :)
I’m not quite sure how iconv works. Do the tests for the permalink_fu plugin pass?
The tests pass but if I try with others accented characters like é or ù the tests fail (é is converted to -e and ù to -u. That’s weird because when I create an article these accented characters are just deleted).
