I was recently asked to modify the GECOS field in the passwd file for a certain user so that it will contain his name with his original accented characters. My first was reaction was "sure, why not?" but then I started getting paranoid that there will surely be a *nix utility that will fail to parse the passwd file because of UTF-8 characters.
So my question is, have you ever ran into any problems using UTF-8 in the passwd file? Or do you know of any?
My locale is set to UTF-8 on all boxes. ( $LANG=en_US.UTF-8 )
