Sorry, I make a mistake.
If uim use only UTF-8, EUC-JP and ShiftJIS(cp932),
resetting the state is specially unnecessary, probably.
I forgot to check whether it was able to be applied to uim or not.
Ummm...
Excuse me but I have no idea that there are any OS or emacs-el that uses
ISO-2022-JP for locale in OS or encoding in emacs-el.


Anyway, in generally, resetting a state is required when using iconv.
I do not found a document clearly described.
But some documents said implicitly.

In libiconv-1.11, testing code and command-line tool.
libiconv-1.11/tests/table-from.c: line from 56 to 58
libiconv-1.11/tests/table-to.c: line from 70 to 72
libiconv-1.11/src/iconv.c: ... so many, snip.

Sun docs, man pages section 3 iconv(3c).
In example, resetting a state using INIT_SHIFT_STATE() macro.

Thank you.
