Thank you for your response.

I'm afraid the cause of this bug is not in glibc.
I found a check with using wcwidth() is wrong at line 55
in ./ncurses/widechar/lib_cchar.c.

At that line, setcchar() returns ERR when wcwidth() returns negative value.
Because wcwidth() returns -1 when a wide character is non-printable,
setcchar() returns ERR if control character is given.
