Arguably the use of yen-sign and macron are at the glyphic variant
level (I know that's not what the mapping tables say), since they
are used as if they were backslash and tilde by Japanese software.

SJIS is stateful, but it doesn't have *shift* states. Although you
must start at an aligned position, you need not know what has come
before. Full ISO 2022 systems don't have this property.
