Dingbats are old school t1 without proper names so we can't use
unicodes. However, there is a goodie that should do that so that in
principle it should work with unicodes but there is some interference
going on (i'll look at that)

For nwo access by 'name' or 'index' (these are kind of stable for such
an old font):

      n:a34  : \getglyph{ZapfDingbats}{\tochar{n:a34}}  \par
      n:a35  : \getglyph{ZapfDingbats}{\tochar{n:a35}}  \par
      i:48   : \getglyph{ZapfDingbats}{\tochar{i:48}}   \par
      i:49   : \getglyph{ZapfDingbats}{\tochar{i:49}}   \par
      n:a104 : \getglyph{ZapfDingbats}{\tochar{n:a104}} \par
      n:a105 : \getglyph{ZapfDingbats}{\tochar{n:a105}} \par

Thank you Hans!
 
Access by glyph index with \tochar{i:19} works well for both MKIV and LMTX. Access by name with \tochar{n:a39} does not work in LMTX with log message: char ✓ (U+02713) in font 'ZapfDingbats-4' with id 8: missing. Also \ShowCompleteFont does not report any glyph names in LMTX.

Cheers,
