Indeed, that was the problem. I reduced the buffer size to 1, since
characters that produce multiple glyphs can't be handled properly by
uniscribe_encode_char, but passed in a size of 20 (a number I'd picked
after I'd come across Indic characters that produce more than the 2
glyphs I'd originally allowed for) to the system function. It might
explain some of the unexplained display corruption I was seeing with
some Indic characters that I had to work around, so I may be able to
simplify that function now.
