Can it be trained to recognize symbols like è,ô, ü?

[zwz]

I just found http://cat.prhlt.upv.es/mer/ and could not wait to test it.
It is amazing. Very impressive.

And then I read the "accepted expressions" part on the web page.
It does not mention the vector symbols with arrow above, or characters like è,ô, ü that are frequently used (at least in my writings).

So will you support it in the near future?
