Do you know how to get greek characters to display correct in a pdf correctly using the Safari Browser

kenlyn: …once I generated the FM file into a pdf and view in the Safari browser, the majority of the greek characters that I use from the Equation palette in FrameMaker is not displaying correctly.

How are they presenting?

And do you have an option to use an external MathML editor to create them?
The FM Equation feature is getting more that a bit creaky.

Where are you getting the Symbol font under Windows? Adobe has a Symbol font available but it is simply named “Symbol” and it may be conflicting with the Mac default Symbol font.  

There is an OpenType version of Symbol (Symbol Std) available for purchase from Adobe that won’t conflict with the Mac version.

You could try a different font, such as Google’s Noto Sans Math. I would set it to Always Embed in Distiller. 

Safari’s built-in PDF viewer uses Apple’s native rendering engine, which frequently struggles to display non-English characters if the PDF creator didn't fully embed the correct fonts (such as Unicode or Symbol fonts) into the document. And the solution I’m seeing online is the same thing Jeff already mentioned—use the High Quality preset to fully embed the fonts.

Sounds like Safari has a hard time figuring out fonts in PDFs if the font is unfamiliar. Google says to try to create PDFs that are set to High Quality and embed the fonts in them. How are you creating the PDFs out of FM?
