Locale

This is closely related to unicode but defines what language
is being used by the user.

Environment vaiables...
  export LANG="en_AU.UTF-8"  # sets all the other LC_types that are not set

See the results using the command "locale"

However one should be set to modify sorting behaviour
  export LC_COLLATE=C        # sets the sorting order for things like "ls"

Setting this to something else will place all 'A's together regardless of
case, or the '.' prefix.

For example...

  > LC_COLLATE="C" ls -a
  .  ..  .CCC  .ccc  AAA  BBB  aaa  bbb
  > LC_COLLATE="en_US" ls -a
  .  ..  aaa  AAA  bbb  BBB  .ccc  .CCC

Also may like to set
  LC_TIME=???
Which effects output of dates and times from "date"


XTerms need to be started with a UTF unicode font.
For example.
  xterm -fn -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1
or
  normal:  -misc-fixed-medium-r-*-*-15-*-75-75-c-90-iso10646-1
  bold:    -misc-fixed-bold-r-*-*-15-*-75-75-c-90-iso10646-1
