[Mediawiki-l] A very short url and the ampersand

Hi, I'm using the very short url method (http://meta.wikimedia.org/wiki/ Using_a_very_short_URL) and, overall, it seems to work. However, any article that uses an ampersand doesn't work. E.g., for an article like "First & Last Tavern", MediaWiki interprets it as "First ". The link shows up as: http://. . ./First_%26_Last_Tavern With Wikipedia, it interprets ampersands correctly, and it doesn't change to %26 in the url. I tested another wiki, which I think uses the same method and it also has the problem of the truncating ampersand, but it doesn't convert the & to %26. Hrm. How can I fix this problem? Thanks! Vernon
