C23 changed char8_t from char to unsigned char, hence assigning a u8 literal
to const char* emits pointer sign warning, e.g.
========
../src/shared/qrcode-util.c: In function ‘print_border’:
../src/shared/qrcode-util.c:16:34: warning: pointer targets in passing argument 1 of ‘fputs’ differ in signedness [-Wpointer-sign]
16 | #define UNICODE_FULL_BLOCK u8"█"
| ^~~~~
| |
| const unsigned char *
../src/shared/qrcode-util.c:65:39: note: in expansion of macro ‘UNICODE_FULL_BLOCK’
65 | fputs(UNICODE_FULL_BLOCK, output);
| ^~~~~~~~~~~~~~~~~~
========
This introduces UTF8() macro, which define u8 literal and casts to consth char*,
then rewrites all u8 literal definitions with the macro.
With this change, we can build systemd with C23.
