On 24 March 2013, this has been read 615 times. Seems like there are people interested in Unicode support. :-)
At present, it is (in my experience) not possible to key in Unicode characters. Files with diacritical characters in Unicode can appear in the result page, but the diacritical characters shows up as its non-diacritical equivalent (E.g. jhāna shows up as jhana.)
I'm okay with it until this point. The real issue for me is that it's not possible to launch such files. So, I'm looking another launcher that does not have this limitation.
