Martin Sebor commented on STDCXX-860:
-------------------------------------
That the characters are really missing (and that the {{locale}} utility isn't
lying) can be confirmed using the program below:
{noformat}
$ cat t.cpp && ./t ./ctype
#include <cstdio>
#include <locale>
int main (int argc, char *argv[])
{
const std::locale loc (1 < argc ? argv [1] : "");
const std::ctype<char> &ct = std::use_facet<std::ctype<char> > (loc);
const std::ctype_base::mask masks[] = {
ct.lower, ct.space, ct.print, ct.cntrl, ct.alpha,
ct.digit, ct.punct, ct.graph, ct.xdigit
};
for (unsigned i = 0; i != sizeof masks / sizeof *masks; ++i) {
std::printf ("%#x: ", masks [i]);
for (unsigned j = 0; j != 256; ++j) {
if (ct.is (masks [i], char (j)))
std::printf ("\\x%02x ", j);
}
std::putchar ('\n');
}
}

> localedef: missing characters for an ellipsis in LC_CTYPE
> ---------------------------------------------------------

> Key: STDCXX-860
> URL: https://issues.apache.org/jira/browse/STDCXX-860
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 4.2.0
> Reporter: Martin Sebor
> Priority: Critical
> Fix For: 4.2.2
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> The {{localedef}} utility appears to skip characters specified using the
> ellipsis in the {{LC_CTYPE}} section. The output below was obtained on
> Solaris 10 (the "couldn't set locale correctly" messages are written out by
> libc). The number of characters specified in the {{ctype.src}} source file is
> 6 ('a', 'b', 'c', 'd', 'e', and 'f'). The output of the {{locale}} utility
> shows that the generated locale contains only the last three characters ('d',
> 'e', and 'f').
> {noformat}
