It seems that there is a bug in unicode collation using tr to convert char to
uppercase :

manu at arcadia> echo $LC_ALL                                                      
en_US.UTF-8
manu at arcadia> echo test | tr '[:lower:]' '[:upper:]'
TEST
manu at arcadia> echo test | tr '[:alpha:]' '[:upper:]'                            
ÓÄÒÓ
manu at arcadia> echo test | tr '[:alnum:]' '[:upper:]'                            
ÞÎÝÞ
manu at arcadia> export LC_ALL=C
manu at arcadia> echo test | tr '[:lower:]' '[:upper:]'                            
TEST
manu at arcadia> echo test | tr '[:alpha:]' '[:upper:]'
