Don't mangle non-Japanese chars which appear after a 'combining' kana in SJIS-2004
Unicode has 'combining' characters which join with another following character.
Japanese hiragana and katakana with the 'two dots' voice mark can be represented
in this way, with one Unicode character for the 'base' kana and another one which
adds the voice mark.
In SJIS-2004, however, there are dedicated characters for voiced and unvoiced
kana. So some special checks are done to identify sequences of Unicode characters
which need to be 'collapsed' into a single SJIS-2004 character.
If a kana is immediately followed by some other unrelated character, like a
Cyrillic letter, then the cached kana should be output 'as is' and we
proceed with encoding the unrelated character. When doing this, though,
we need to re-initialize local variables, or else the unrelated character
will be mangled in some cases.
