LC_CTYPE=C should be sufficient.

What comes to mind is pstree. Running it in a terminal you get a tree of
unicode characters, piping (or redirecting) you get ascii characters.

Basically it is a matter of preference. I would prefer ascii for a
non-terminal to make sure you can view a redirected text file without issue
even if unicode is not supported.
