In C?  Of course it is.  (Never in Lua--an extension language can't be
changing the locale environment, since it's shared by its parent.)

GNU grep is much slower in UTF-8 than without multibyte support.  :(

Huh?  Lua is written in C, not Java or Tcl.  There are "portable" mechanisms
for localization (eg. wctomb(), wcwidth(), wchar_t and friends), but not
all systems have them (Windows, embedded systems, etc).
