+;; Unicode in strings, using ascii
+"\u03bb" ; -> "λ"
+;; and since Racket source code is read in UTF-8, Unicode can be used
+;; directly
+"λ" ; -> same
+
+;; The same holds for character constants
+#\u3bb ; -> #\λ
+#\λ    ; -> same
+
+;; And of course Unicode can be used in identifiers,
+(define √ sqrt)
+(√ 256) ; -> 16
+;; and in fact the standard language makes use of some of these
+(λ(x) x) ; -> an identity function
