Getting backtraces against this assertion isn't useful at all.
Fontconfig isn't capable to report who really have a reference
of caches though, this report may be better than assertion.
So we can try analysis tools then.
And report it only when running with FC_DEBUG=16.
LC_CTYPE is set to "UTF-8" on some macOS systems, which is
POSIX-compliant in a strict sense, but breaks the usual assumption
that a locale name has the form "ll_LL.encoding".

Previously, this would cause the warning
Fontconfig warning: ignoring UTF-8: not a valid region tag
Now, we just skip this variable if set to "UTF-8", since that value
doesn't give any language information, and move on to try LANG.
The forked repository is unmaintained and several releases out of date.
The upstream repository now includes meson support, so the forked
repository is no longer necessary.
modifies the gperf test to instead rely on a file input
rather than piping in using sh, as sh is often not reliable
on Windows due to paths.
Also changes the if else ladder into a foreach loop.

Stripping the first char of a path to make it relative only works with
UNIX paths like '/prefix' but not with Windows paths like 'c:\prefix'.
This copies the code Meson uses.
Sometimes we might want to build docs (install man pages, etc)
but allow disabling use of docbook.

The ctype(3) functions take arguments of type int that are either
(a) EOF, or
(b) unsigned char values, {0, 1, 2, ..., 255} if char is 8-bit.
Passing values of type char, on platforms where it is signed, can go
wrong -- negative values may be confused with EOF (typically -1) or
may lead to undefined behaviour ranging in practice from returning
garbage data (possibly out of an adjacent buffer in memory that may
contain secrets) to crashing with SIGSEGV (if the page preceding the
ctype table is unmapped).
The ctype(3) functions can't themselves convert to unsigned char
because then they would give the wrong answers for EOF, for use with
functions like getchar and fgetc; the user has to cast char to
unsigned char.
