The Dockerfile said `fr_FR.UTF-8`. PHP saw `C.UTF-8`.
The value observed here, C.UTF-8, isn't the bare C locale either: it's a UTF-8 variant of the POSIX locale. It remains distinct from the ICU locale used by ext-intl, which resolves its own default locale independently of LC_CTYPE. iconv(), on the other hand, depends directly on the process locale set by the libc.

> You can't even clearly define what an "atomic sequence of glyphs" is.
Kinda. Grapheme cluster breaks are defined in Unicode, but they have all the baggage and edge-cases you'd expect from human languages evolving over time, so they can be encoded in as a few as a thousand rules : https://github.com/unicode-org/icu/tree/main/icu4c/source/da...

C Macro Reflection in Zig – Zig Has Better C Interop Than C Itself
This sounds amazing, and it's great that tooling is so strong of some "new kids on the block" (Zig, Rust), even better than C.
With hindsight, it is strange that the C community, with all the people and money behind it (and what scale!) never even managed to build a proper packaging manager (okay, there's now Conan, but that came from Python guys).
But then, there even still isn't a perfect C string library around (something that would combine GLib, SDS, ICU, say, and then standardize it in C2038).

Get wide characters one by one from a char * string
If you want graphemes, something lile libgrapheme might suit you. If just code points, then the utf8.h from ICU can work, but you can also roll your own if needed.
