spot the language

Someone wrote to my favorite list,

I received this spam today. Does anyone know what language it is? (And is there a tool, pref. on the web and free, that can take a piece of text and guess what language it’s written in?)

I’d never have thought to look for such a tool, but Lance Nathan came through with three:

• ¿Qué?, the System for Identification of Language and Character Encoding
• Système d’Identification de la Langue et du Codage
• Content Analysis Language Identifier
