Right now I'm reviewing this answer and I don't know what to do:
http://superuser.com/a/792377/180465

The problem is - it's written in another language (but with english letters) and it's impossible to understand what's written there.
So it can be:

• A real answer, but in another language (I must leave a comment or edit to make it english)
• Spam (add a spam flag)
• Not answer (mark as not-answer)

etc.

So, how to deal with such questions/answers? How to flag these questions?
(P.S. currently I've left a comment for him to write in english)
