I am not sure... How do you enter a literal "\u20AC" then in the environment?
setenv EURO "\\u20AC"?
Does not seem very intuitive to me. At least we have simple "output" semantics
here for echo. What would be the "input" semantics, and which commands do they
affect? I.e. does the translation happen for all variables on assignment? For all
literal strings present in csh code?
