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.
