I just read on the Xepher forums that PHP/MySQL on the server had been down for several hours while I was sleeping. This means that in all likelihood, the Rogues of Clwyd-Rhan comic wasn't working, although it may actually have reverted temporarily to the Movable Type-based version, which builds an index.html file. Apologies for the downtime, if you noticed any.
Update: It looks like the changes to the database settings have caused the titles and possibly all the typed text within episodes to be presented as ASCII characters instead of the Unicode encoding they need to be. I've alerted Xepher to this.
Now's as good a time as any to link to an article Pete Ashton linked to a while ago: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!). If you're a software developer, learn this. If you're the customer of a software developer, have someone carve this into a baseball or cricket bat, the better to bludgeon your developer with if they get it wrong. Please.
