Strange Characters in Comments

I’ve started receiving a strange type of comment spam recently which looks like a big mess of funny characters:

I’m pretty sure it’s spam in a different character set, as I can spot the occasional term that indicates what it is, from diet pills all the way to trade show exhibits; from PC specifications to cheap toys from China. And I’m suspecting that the characters might actually be Chinese, based on the origination of the comments.

Anyway, time to deploy Bad Behaviour. It’ll let you know if it cleans up the problem.
