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.
