Would it break backward compatibility for C to add a feature like this
from Python? Namely, the ability to check if a value lies in an interval:
      def valid_char(c) :
         "is integer c the code for a valid Unicode character." \
         " This excludes surrogates."
         return \
             (
                 0 <= c <= 0x10FFFF
             and
                 not (0xD800 <= c < 0xE000)
             )
     #end valid_char
