TTF single line font not working in Rhino3D _Text command (not _TextObject)

[DonatF]

It should be possible to use this font in the _Text command in Rhino. Although _TextObject works OK with this font, the text can't be edited after creation. It is also harder to integrate with grasshopper.
This is the observed behaviour with Relief-SingleLine:

This is the expected behaviour using RHSS font as an example:

I am getting the impression that Rhino siomply maintains a list of known single line fonts in their code, so your font is not on that list yet, so it doesn't render properly in the _Text tool. the solution appears to be to communicate with McNeel, so that they add it to the list.

Our TTF export should work in Rhinoceros 3D, make sure you are selecting the / Allow single stroke fonts option in the Text Object dialog box, see some screen captions in Rhino 7 evaluation version in this folder.
