Created attachment 904862 [details, diff] 940705.patch Might be an upstream bug? Which would be very weird since they claim Mac compatibility which obviously also uses libcxx. Seems like libcxx does not define std::char_traits<unsigned char> (the standard does not require this) while libstdcxx does, at least a small test program that makes a basic_string<unsigned char> compiles, so that's why it works with a GCC toolchain. I've managed to make it compile, though. See attached patch.
Seems like this is a change in libcxx 19. Bug 939897 is the same issue for media-libs/zxing-cpp and has an explanation.
