strange tr behaviour

[Michael Reifenberger]

Hi,
under -current with the following env settings:
	LC_ALL=de_DE.ISO8859-15
	LC_CTYPE=de_DE.ISO8859-15
	LANG=de_DE.ISO8859-15
using tr as follows I get:

# echo "abcdefghijklmnopqrstuvwxyz" | tr '[a-z]' '[A-Z]'
ABCDEFGHIJKLMNOPQRSUÚWXYÝ]

but:

# echo "abcdefghijklmnopqrstuvwxyz" | tr '[:lower:]' '[:upper:]'
ABCDEFGHIJKLMNOPQRSTUVWXYZ

AND:

# unsetenv LC_ALL
# unsetenv LC_CTYPE
# unsetenv LANG
# echo "abcdefghijklmnopqrstuvwxyz" | tr '[a-z]' '[A-Z]'
ABCDEFGHIJKLMNOPQRSTUVWXYZ


?!?
Anyone else?
Anyone any clue?

Bye/2
