Step 1 of the Hangul Syllable Composition algorithm on page 54 of
the Unicode Standard 3.0 doesn't do anything. It reads:
# 1. Process D [the decomposed form] by composing the conjoining
# jamo wherever possible, according to the compatibility decomposition
# rules in Chapter 14, Code Charts.
However, there are no such compatibility decompositions, and haven't
been since at least 2.1.9! I suggest replacing this step by something
like the following:
1. Process D by composing certain sequences of conjoining jamo
into single jamo, according to the following special table.
The sequences given here represent neither canonical nor
compatibility decompositions, and exist solely for the purposes
of this algorithm.
Typical interchange of conjoining jamo may not require this step,
but composing raw keyboard data may.
