    // Hiragana-Katana
    
    // 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 the 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 natural language expectations.
