This is the case that X/Open Curses documented.

the parameter is in the range 128\-159, i.e., a C1 control code.

+If \fBuse_legacy_coding\fP(3X) has been called with a \fB2\fP parameter,
\fBunctrl\fP returns the parameter, i.e., a one-character string with
the parameter as the first character.
Otherwise, it returns \*(``~@\*('', \*(``~A\*('', etc.,
printable.
This implementation uses 8 bits but does not modify the string to reflect
locale.

Likewise, the \fBmeta\fP(3X) function allows the caller to change the
output of \fBkeyname\fP, i.e.,
it determines whether to use the \*(``M\-\*('' prefix
for \*(``meta\*('' keys (codes in the range 128 to 255).

X/Open Curses does not document the treatment of codes 128 to 159.
