Well, the list of `official' glyph names which contains `small' in its
names (like `Asmall') is Adobe's glyphlist.txt. This list is frozen.
Any other font which contains glyphs with a trailing `small' in its
name is non-standard which consequently means that you need a bunch of
\pdfglyphtounicode calls anyway. However, this is my personal
Which OpenType fonts do you have in mind if you say `such names are
pretty common'? Normally, glyphs like `Asmall' are called `A.small'
in recent fonts.
