well for example, you can use "read", as you did.

another way is to use od or xxd and run it "interactively". The first tests
your shell, the latter tests the ability of your kernel.

The only kernel with utf-8 support that I know of (there might be others)
is Linux. On those systems, urxvt will automatically set the utf-8 flag
(see man stty), if you had new enough kernel and header files, but you cna
also set it afterwards.

For the shell, check your locale settings. A nice way to test is "perl -e0",
this should not output any locale-related error message, and your locale
should use an utf-8 encoding.
