# Hiragana-Katakana
# This is largely a one-to-one mapping, but it has a
# few kinks:
# 1. The Katakana va/vi/ve/vo (30F7-30FA) have no
# Hiragana equivalents.  We use Hiragana wa/wi/we/wo
# (308F-3092) with a voicing mark (3099), which is
# semantically equivalent.  However, this is a non-
# roundtripping transformation.
# 2. The Katakana small ka/ke (30F5,30F6) have no
# Hiragana equiavlents.  We convert them to normal
# Hiragana ka/ke (304B,3051).  This is a one-way
# information-losing transformation and precludes
# round-tripping of 30F5 and 30F6.
# 3. The combining marks 3099-309C are in the Hiragana
# block, but they apply to Katakana as well, so we
# leave them untouched.
# 4. The Katakana prolonged sound mark 30FC doubles the
# preceding vowel.  This is a one-way information-
# losing transformation from Katakana to Hiragana.
# 5. The Katakana middle dot separates words in foreign
# expressions; we leave this unmodified.
# The above points preclude successful round-trip
# transformations of arbitrary input text.  However,
# they provide naturalistic results that should conform
# to user expectations.

# Katakana followed by a prolonged sound mark 30FC has
# its final vowel doubled.  This is a Katakana-Hiragana
# one-way information-losing transformation.  We
# include the small Katakana (e.g., small A 3041) and
# do not distinguish them from their large
# counterparts.  It doesn't make sense to double a
# small counterpart vowel as a small Hiragana vowel, so
# we don't do so.  In natural text this should never
# occur anyway.  If a 30FC is seen without a preceding
# vowel sound (e.g., after n 30F3) we do not change it.
