Hi,
I'm Ben and implemented modules support in CMake, authored P1689 itself,
its support in GCC, and helped wrangle its support into clang and MSVC.
I encourage you to read this paper:

Hi,
I tried adding isl 0.26 to a 13.2 GCC build using Iain's macOS aarch64

It seems that the bootstrap's `CXX='g++ -std=c++11'` confuses isl's

FWIW,
This patch implements support for [P1689R5][] to communicate to a build
system the C++20 module dependencies to build systems so that they may
build `.gcm` files in the proper order.
Support is communicated through the following three new flags:
- `-fdeps-format=` specifies the format for the out
This simplifies the interface for other UTF-8 validity detections when a
simple "yes" or "no" answer is sufficient.
libcpp/
* charset.cc: Add `_cpp_valid_utf8_str` which determines whether
a C string is valid UTF-8 or not.
* internal.h: Add prototype for `_cpp_valid_utf8_s
Unicode does not support such values because they are unrepresentable in
UTF-16.
libcpp/
* charset.cc: Reject encodings of codepoints above 0x10.
UTF-16 does not support such codepoints and therefore all
Unicode rejects such values.

Hi,
This patch adds initial support for ISO C++'s [P1689R5][], a format for
describing C++ module requirements and provisions based on the source
code. This is required because compiling C++ with modules is not
embarrassingly parallel and need to be ordered to ensure that `import
some_module;` can

This routine has a lot more logic (including UCN decoding) and the
`one_utf8_to_cppchar` also supports out-of-bounds
