Subject: [ruby-talk:30347] How to convert character code to a String?

Hi there,

I fear I might be missing something obvious, but I'm wondering how to
get a one-character String with a given character code.  By examining
the pickaxe book and the archive of this mailing list, I've found this
so far:

	c = 123
	s = String.new
	s << c
	list_of_strings.push(s)

This is a bit verbose, and I hope I can do something like the
following instead of the above:

	c = 123
	list_of_strings.push(char(c))

It's relatively easy to obtain character codes (String#[]), so I
expect there's a straight forward way to obtain a String from a
character code.  If there's no built-in way, that's OK, and I'll
define a method like "char" above or add an method to the Fixnum
class.

Thanks,
Ryo
