IF you're talking about Sabon LT Std Roman, Open Type, with this 
Version identification,
Version 1.040;PS 001.001;Core 1.0.35;makeotf.lib1.5.4492
  then I think that you're looking for:

0 - 9
Unicode values F643 - F64C

The glyph NAMES are
zero.taboldstyle, one.taboldstyle, etc.

Their decimal indices (INDEX codes) are
330-339 (161-16A Hex)

Note that these are not standardized; the indices are different for 
different fonts, so if you're using them you won't be able to change 
fonts - possibly not even to a different version of the same font.

Depending on what OS you're using and what applications you have, you 
should be able to find information like this. For example, in Windows, 
the included Charmap application can display the unicode values.

Thanks Herb!

Here's the info I have on the font.

/home/jeff/.fonts/SabonLTStd-Roman.otf: :fullname=SabonLTStd-Roman,Sabon LT Std,Sabon LT Std Roman:fontversion=133693

The version info doesn't match, but that could be because we are working in different environments. I'm running linux.

And the unicode values you give below are the ones I've been trying to use. (Found them on the linotype.com site, not Adobe's.)

Using Character Viewer (a linux utility), I can display the character map. However, the taboldstyle characters don't show up at all. They ARE displayed (without codes) on the PDF download for the font from Adobe.

I'll try giving Adobe tech support a call.

Thanks again.

Just to close this off ...

In fact, the characters I wanted _are_ provided in the font and were being displayed by the linux utility Character Map (mislabeled Viewer by me). They are stashed under the 'Common' Script, not under 'Latin'.
