I think there are actually two problems going on here:

• The developer's name contains unicode characters that Recipe Robot isn't handling properly, and
• The download format is .tar.xz, which Recipe Robot doesn't know what to do with.

The first issue can be solved by properly handling unicode all the way through Recipe Robot, which I admit I'm not as knowledgeable about as I should be. Seems to me that developers should be encoded as unicode by default, except when they need to be strings (POSIX paths?). I'll look into this.

The second issue is trickier. Even if Recipe Robot knows that .xz is a compressed archive, it won't do much good in this situation because the Unarchiver processor doesn't. Meaning: you can't use AutoPkg to process this app's Sparkle feed without writing a custom processor.

(If somebody wanted to add .xz format support to Unarchiver, I suspect that this code would be a good start.)
