-@defun char-to-string character
-@cindex character to string
-This function returns a new string containing one character,
-@var{character}. This function is semi-obsolete because the function
-@code{string} is more general. @xref{Creating Strings}.
-@end defun
-
-@defun string-to-char string
-@cindex string to character
- This function returns the first character in @var{string}. If the
-string is empty, the function returns 0. The value is also 0 when the
-first character of @var{string} is the null character, @acronym{ASCII} code
-0.

-@example
-(string-to-char "ABC")
- @result{} 65
-
-(string-to-char "xyz")
- @result{} 120
