1) File names in Unicode: no (well, the Linux kernel is 8-bits clean
so you can always encode in UTF-8, but the kernel does not do any
normalization and the applications do not expect UTF-8, for instance
ls sorts alphabetically but dot not know Unicode sorting).
2) User names: worse since utilities to create an account refuses
3) grep: no Unicode regexp
4) xterm (or similar virtual terminals): No BiDi support at all
5) shells: I'm not aware of any line-editing shell (zsh, tcsh)
that have Unicode character semantics (back-character should move one
character, not one byte)
6) databases: I'm not aware of a free DBMS which has support for
Unicode sorting (SQL's ORDER BY) or regexps (SQL's LIKE).
7) Serious word processing: LaTeX has only very minimum Unicode
Also, many applications (exmh, emacs) are ten times slower when
running in UTF-8 mode.
At the present time, using Unicode on Unix is an act of faith.

Yes, RedHat changed the default charset to Unicode without thinking
that text files were no longer readable.
