CoreText: determine symbol's characteristics: diacritic/space/cluster/wordbreak/etc

Hey there,

I am currently having trouble determining the characteristics of the
symbols,
which is being processed by CoreText framework:

I need to know if specific symbol is diacritic, or space.
Whether is ends a word, cluster, etc.

Normally in Uniscribe there is output structure (GCP_RESULTS), which has
all that info packed into 1 single structure and it is easy to know by
iterating by structure's contents.

Ideally, I want to know same amount of information about the string/glyphs
being processed - it would be great to know how to extract it.

Thanks,
ernie
