These are all as expected:

% echo \u20ac
u20ac

% echo "\u20ac"
€

% echo '\u20ac'
€

% echo "\x20ac"
 ac

% echo "\x{20ac}"
€

% setenv EURO "\u20ac" ; echo $EURO
€

% setenv EURO "\x20ac" ; echo $EURO
 ac


This is not:

% setenv EURO "\x{20ac}" ; echo $EURO
 ac

If not a bug, could you explain why?
