According to "info libc", the following expressions should be allowed:
yesexpr "^([aA][lL][rR][eE][aA][dD][yY]|[cC][oO][rR][rR][eE][cC][tT]|[yY][eE][sS])"
yesexpr "^([nN][oO]|[iI][nN][cC][oO][rR][rR][eE][cC][tT])"

In this case, I would however recommend to use a shorter form since there
is no ambiguity after the first char:
yesexpr "^[aAcCyY]"
noexpr "^[nNiI]"

I assume there may be some languages where one of the YES forms starts with
the same character than one of the NO forms. In that case, a longer regex
could be useful.

Of course, the long form force the user to type more than one character.
But any application that checks the answer with rpmatch or regex should

There are probably some applications which assume there may be only one
char, but I would say they are not internationalize the right way, and
should be fixed.

No, the regex is not right. It should be written:

(brackets means a choice between some characters, and parenthesis with
bars (|) means a choice between a sequence of characters).

And thanks Clytie for demonstrating a language with a YES form (Có)
starting with the same character than a NO form (Chưa) ;)
So [cC] is not correct and shorter regex should work:

Clytie, do you have a way to test it?
Otherwise, I will test it later.

Kind Regards,
