make-char is an obsolete function that makes no sense at all in
Unicode-based Emacs. Don't use it. And it wouldn't have helped you,
because it returns the numerical code point of the character. That's
because in Emacs, a character is just an integer, so every function
that _creates_ characters always returns an integer value.
What you want is not the character, but its string representation.
That's what prin1-char is for.
