Right. I think I had read somewhere that in Mac OS X environment
variables aren't set in the shell's startup file, but rather in the ~/
MacOSX/environment.plist file. Coming from Linux, I put the LC_*
variables in the shell's startup file, and forgotten to remove them
after. Should I put them in ~/MacOSX/environment.plist?

I understand. Unfortunately it seems that this is not the case, as the
path doesn't seem to contain any Greek characters that might be
decomposed; there are only capital Greek letters without any
diacritics (only some plain underscores in between). (The name of the
file itself contain only latin characters.)

Doing as you suggested, with C-u C-x = on the directory, I get the
following:
---------------------------------------------------------------------------------------------------------------------------------
character: SPC (32, #o40, #x20)
preferred charset: ascii (ASCII (ISO646 IRV))
code point: 0x20
syntax: which means: whitespace
category: a:ASCII graphic characters 32-126 (ISO646 IRV:
1983[4/0]) l:Latin
buffer code: #x20
file code: not encodable by coding system nil
display: by this font (glyph code)
DejaVuSansMono (#x03)
Character code properties are not shown: customize what to show
There are text properties here:
auto-composed t
fontified t

I checked, and no MULE references exist in the .emacs file.
