Michael Paquier 82116023e4 Fix off-by-one with NFC recomposition for Hangul U+11A7 (TBASE) 
The NFC recomposition incorrectly included TBASE as a valid T syllable,
which is incorrect based on the Unicode specification (TBASE is one
below the start of the range, range beginning at U+11A8).

This would cause the TBASE to be silently swallowed in the
normalization, leading to an incorrect result.

A couple of regression tests are added to check more patterns with
Hangul recomposition and decomposition, on top of a test to check the
problem with TBASE.  Diego has submitted the code fix, and I have
written the tests.
