I used to export my SMS using:

This used to export the unicode characters no problem. But I ran it today and i just get question marks where I used to see the Chinese characters in my messages.

How can I export my SMS with the unicode encoding intact, and what has changed to make this command now print "???" instead of unicode.

NOTE: Even redirecting stdout to a file and opening that file gives me question marks. tracker-sparql actually writes "???"!
