linux don't display them, the shell (emulator) do. Linux just send the bytes back to userland and let shell interpret them with a proper format to human. And even then. Tons of distro default the global LANG to c for some reason. So utf8 display isn't even working by default.

Even better: Each user can have his own locale and charset, and may even change that per program/shell/session. One may save filenames as UTF-8, one as ASCII, one as ISO8859-13, one as EBCDIC.

However, the common denominator nowadays is UTF-8, which has been a blessing overall getting rid of most of the aforementioned mess for international multi-user systems. And there is the C.UTF-8 locale which is slowly gaining traction.
