OK, I agree.
My fonts tab shows either Tahoma or some AvantaGarde (which matches when I checked online) and I have no clue how the later comes into picture since it is not installed on my system.
I think font mapping, as in the case of DWG, is not exposed yet, hence this appears to be some internal mapping.
I can only speculate that Siemens doesn't want their drawings to look like Solidworks. Kinda bums me out as I think Century Gothic is very clear and easy to read on a drawing.
Ah, I see now, it's in the "Callout Text" area.....yes, I get the same result.
I remember on my old computer, I had Adobe Pro suite, and the print to PDF functionality it had, also allowed the option to embed fonts. I suspect this is what is happening here, or rather, "not", during the Save As - PDF in Solid Edge.
