I was wondering about a third-party script which always
worked for years with Solaris. I just didn't realized that
this issue concerns a difference between SysV and BSD.

I tried to set another LANG string and it worked, but now
I see that it will work this way with an arbitrary string,
because it's invalid. ;-)
