# 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.
|
|
