Performs a single decomposition step of the
Unicode canonical decomposition algorithm.
This function does not include compatibility
decompositions. It does, however, include algorithmic
Hangul Jamo decomposition, as well as 'singleton'
decompositions which replace a character by a single
other character. In the case of singletons *b will
be set to zero.
If ch is not decomposable, *a is set to ch and *b
is set to zero.
Note that the way Unicode decomposition pairs are
defined, it is guaranteed that b would not decompose
further, but a may itself decompose. To get the full
canonical decomposition for ch, one would need to
recursively call this function on a. Or use
g_unichar_fully_decompose().
See UAX#15
for details.
