This is probably a pretty basic question, but how do I find out the

Hi Sandra,

the only reliable method I have found is to inspect the font with
FontForge.

Here is an example: the Swiss 721 font from Bitstream (Helvetica
digitization).

FontForge reports:

Font name:    Swiss721BT-Roman
Family name:  Swis721 BT
Display name: Swiss 721 BT
Weight:       Book

"mtxrun --script fonts --list --all --pattern=swiss" result:

swiss721bt                  swiss721btroman             Swiss721.ttf
swiss721btroman             swiss721btroman             Swiss721.ttf

The only name which works in ConTeXt is the family name (which can be
seen in FontForge): "Swis721 BT", note the single "s".  However, this
name is *not* shown in the mtxrun output.

Interestingly, I have also seen mtxrun show the family name (different
from the font name) for other fonts, so I really do not know how it
makes up its output.  It is certainly not useful to find out the
name that is to be used in ConTeXt.
