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.
libmbfl
This is libmbfl, a streamable multibyte character code filter and converter library, written by Shigeru Kanemoto.
The original version of libmbfl is developed and distributed at https://github.com/moriyoshi/libmbfl under the LGPL 2.1 license. See the LICENSE file for licensing information.
The libmbfl library is bundled with PHP as a fork of the original repository and is not in sync with the upstream. As such, the libmbfl directory is directly modified in the php-src repository.
