Strings are said to consist of printable characters, except that the 
backslash escape codes can be used for non-printable characters.  Is this 
actually necessary?  As long as I put escapes in front of quotes, 
apostrophes, and backslashes (because they are lexically significant, it 
seems silly for me to convert other characters to hexadecimal so that the 
back end can convert them back.

Characters (but not strings) seem to be able to involve more than eight 
bits.  But there seems to be no way of providing more than eight bits for 
a character.  Do they get zero-extended?  Or sign-extended?  Or if I have 
a larger-than-eight-bits character set available, am I just better off 
coding them all as integers?
