Non-english characters on default search

[nbasili]

When typing a text with non-english characters on an empty visual search input, without a facet selected, the default text: ... facet does not get filled in and the text typed is lost.

Works fine for english words though.

For example:
| John | -> Enter -> | Text: John |
| Γιάννης | -> Enter -> | access: | (returns the first facet)

I'm having trouble replicating the issue (and our usage in DocumentCloud does appropriately set up a text facet when you paste in Γιάννης or type in other unicode), do you happen to have a page I could hit to see what's happening?

You can try it here:
http://documentcloud.github.io/visualsearch/

Just clear out all fields and type in or paste the non-english text.
It seems that the problem is that when you start typing with non-english characters the facet dropdown does not get cleared out.

For example, if I type 'a' the 'access' facet is displayed. As soon as I press 'v' (av), the dropdown disappears as there is not match for 'av'. But it seems that it fails with other Unicode chars.

So it the url above, if I paste (or type) "John", the dropdown is cleared. If I paste (or type) "Γιάννης", the dropdown stays open with "access" preselected.

Tested on latest Chrome and Firefox.
