boost:::iostream::inverse doesn't work with char_type other then char

[mexal@…]

See file \boost\iostreams\invert.hpp

This lines

std::streamsize read(Source& src, char* s, std::streamsize n)
...
std::streamsize write(Sink& dest, const char* s, std::streamsize n)

should be changed with:

std::streamsize read(Source& src, char_type* s, std::streamsize n)
...
std::streamsize write(Sink& dest, const char_type* s, std::streamsize n)

for appropriate handling of unsigned char, for example.
