Thank you, Kent and Matz!  Yes, I was missing something
(semi-)obvious.

As Kent said, it's Integer#chr.  Of course, Integer is a superclass of
Fixnum....  Just out of curiosity, this makes me wonder why it isn't
Fixnum#chr.  Is that because you envision a future where Ruby handles
four-byte characters (assuming a Fixnum is 31 bits or longer)?

Finally, a feeble excuse :-)  I didn't find #chr because I checked
Fixnum but not Integer.  This is the reason why I said
"(semi-)obvious".

BTW, I bought a copy of "Ruby in a Nutshell" today.  The book is a
nice handy reference.  I'm happy with it.

Thanks again,
Ryo
