Bug? Recently any optimized or extracted pdf by Standard DC generates a cannot find or create the font XXXXXX+ArialMT. Some characters may not display or print correctly. I've only been working with map pdfs produced by ArcGIS, but some of these are new and some quite old and I've never had this problem before. They seem to display properly but it is so annoying to have to click through the warning every time. The XXXXXX differs every time.
