Font Issue

[gglazer-dustyrobotics]

We see when opening our PDFs with Acrobat, the error "There was an error processing a page. There was a problem reading this document (110).". With some web searching this seems to indicate a font error. The files generated with gopdf can be read in the browser, just not in Acrobat Reader, which is consistent with that Adobe thread on the error message.

The fonts we are using are very plain and standard: Courier Prime (from Google) and Helvetica (from font.download).

Do you know why these fonts would fail in reader, or alternatively, do you have a tested source for free fonts that Reader likes?

Thanks,

Glenn
