We set up a NSTextStorage instance containing the string
"Zapfino" using the font Zapfino. We expected the - (unsigned)
numberOfGlyphs selector to return 6, since the characters "pf" should
be presented as a ligature, i.e. a single glyph. However, the
selector returns 7.

In font Zapfino the string "Zapfino" is only one glyph, a long ligature. If you change this word (append a character) then only pf is a ligature (I had fi expected as is in Apple Chancery). Have a look at: <http://developer.apple.com/samplecode/LayoutManagerDemo/ LayoutManagerDemo.html> This app does not show glyphs. It can easily be fixed if you know what the program does.
