Show only works on strings.  To draw a glyph by name use glyphshow
operator.  E.g.

    /r glyphshow

With this approach one have to track the current encoding of the font,
which might prove unwieldy.

Another solution is to use CID keyed fonts (though not all Level 2
printers support CID).  See Adobe tech notes at

    http://partners.adobe.com/asn/developer/technotes/fonts.html

One can construct a composite font from "plain" Type1 fonts and use
CID keys to address glyphs in it.  There's an example in one of
technotes, but I don't remember which one and don't have them handy to
look up.
