That's interesting that it was disputed, because the translated answer (provided by Matt in a pre-delete edit to the answer) looks very low quality to me:
Yii is very scalable, any component can be extended through inheritance, events, behavior, and achieve the same functionality can be used in three different ways. It's great!
Though, to be fair, I don't even see how the question itself or any of the answers have any merit. The question seems to boil down to little more than:
Is Yii good? Should I use it?
Which I just don't see as a good fit for Stack Overflow. The OP comes close to a real question with that last bit:
And the ability to pick and choose when to use it or your own php?
That should really be elaborated and made the specific focus of the question, because that seems (at least to me) to be more specific and answerable with actual examples.
The second answer to which you link, regardless of the presence of a foreign language, just looks like noise to me. I can see where the user is trying to convey some information about where in the API to find a solution, but something seems to have gone horribly wrong when pasting that information into the answer.
In short, I'd say that both of those answers can equally be flagged as Very Low Quality or Not An Answer. Given that Stack Overflow is very much an English-only community, I'd argue that any answer given in a different language is by definition Not An Answer, since it contains no useful information in the language of the site.
For a useful reference, Bill the Lizard posted some information about how flags are generally seen by and processed by moderators. Given that information, you can always flag as Other and give an explanation of why you're flagging it. It might take longer to be seen by a moderator, but would at least provide more context.
