encoding: avoid implicit instantiation of `std::char_traits<unsigned char>`

According to the C++ standard, char_traits is not defined for unsigned
char, so don't attempt to instantiate it. This fixes building against
LLVM libc++ 19 and later, and thus with Xcode 16.3 and presumably also
on other platforms/toolchains that use libc++ by default such as Android
and FreeBSD.
