It looks like it’s `iso-latin-3', which is not working, since all my unicode 
characters get mangled. See [the screenshot in this question of mine on 
StackExchange.]

There is no eo.UTF-8 locale available to the system, as you can see [from the 
glibc documentation]. The “eo” locale is actually UTF-8, however. It’s 
interpreted as such just fine, across my whole system, except for in the emacs 
terminal, where it gets interpreted as `iso-latin-3'.

If you look at that glibc document, you’ll see that the “eo” locale is actually 
UTF-8. Unlike `en_US', which has variants like  `en_US.UTF-8' which is UTF-8 
and `en_US' which is ISO-8859-1, there is only `eo/UTF-8', i.e., `eo' which is 
UTF-8.
