[XeTeX] font licenses and embedding

[maxwell]

I used XeLaTeX to create a PDF.  One of the fonts (SD-TTSurekh) didn't get
embedded.  Presumably this is because its license doesn't allow that.  But
how can I tell whether a given font allows embedding without running it
through xetex?  In particular, otfinfo doesn't seem to provide the info:
