>Description:
	In Hungary, we use the hu_HU.ISO8859-2 locale.  The iso-8859-2
codepage has correct upper-lower conversion tables (eg. in vi, the ~
operator works well, with correct LANG variable), but tr has a bug: it
uses something, but not the correct iso-8859-2 conversion table when
converting from upper to lower or vice versa.

>How-To-Repeat:
	# use correct fonts, kbdtables and LANG, eg:
$ kbdcontrol -l hu.iso2.102keys
$ vidcontrol -f iso02-8x16
$ export LANG=hu_HU.ISO8859-2
$ echo áéíóöõúüû | hd

$ echo áéíóöõúüû | tr '[:lower:]' '[:upper:]' | hd	### INCORRECT!!!
