Fcft no longer uses wchar_t, but plain uint32_t to represent codepoints. Since we do a fair amount of string operations in foot, it still makes sense to use something that actually _is_ a string (or character), rather than an array of uint32_t. For this reason, we switch out all wchar_t usage in foot to char32_t. We also verify, at compile-time, that char32_t used UTF-32 (which is what fcft expects). Unfortunately, there are no string functions for char32_t. To avoid having to re-implement all wcs*() functions, we add a small wrapper layer of c32*() functions. These wrapper functions take char32_t arguments, but then simply call the corresponding wcs*() function. For this to work, wcs*() must _also_ be UTF-32 compatible. We can check for the presence of the __STDC_ISO_10646__ macro. If set, wchar_t is at least 4 bytes and its internal representation is UTF-32. FreeBSD does *not* define this macro, because its internal wchar_t representation depends on the current locale. It _does_ use UTF-32 _if_ the current locale is UTF-8. Since foot enforces UTF-8, we simply need to check if __FreeBSD__ is defined. Other fcft API changes: * fcft_glyph_rasterize() -> fcft_codepoint_rasterize() * font.space_advance has been removed * ‘tags’ have been removed from fcft_grapheme_rasterize() * ‘fcft_log_init()’ removed * ‘fcft_init()’ and ‘fcft_fini()’ must be explicitly called
