Hi,

I'm trying to understand a comment in the source for the Hangul shaper.

Line 155; after denoting the various jamo blocks, it says "Only <LV,T>
sequences for T in U+11A8..11C3 combine."

Why is that? The T jamo extend down to U+11FF (all still in the main jamo
block).

More importantly, perhaps, I can't find a source in Unicode or in the MS
OpenType docs that mentions that specific limitation, either. The MS docs'
appendix B lists compositions for the whole T section.[1]

Is the cut-off from some old standard, or something like that? I can see
that the Syllables block doesn't have every permutation; I'm just trying to
understand why T is getting different treatment than L and V....


Thanks,
Nate
