Forum How do I...?

Mathematical Alphanumeric Symbols converts to '?' character

denislife
I'm using Prince 12.5 on Mac. Before the mac OS and prince tool upgrade everything worked ok. Now i'm getting errors on 2 symbols (alpha and beta). Any idea how to define/install missing font or modify fonts.css?

prince: warning: no font for Mathematical Alphanumeric Symbols character U+1D6FC, fallback to '?'
prince: warning: no font for Mathematical Alphanumeric Symbols character U+1D6FD, fallback to '?'

Thanks in advance.

Can you check which font supports this character? Can the character map / font book tool show this?

i checked the Font Book. There is no such characters in any fonts installed... :(

That is unfortunate! If it is an italic alpha character, perhaps you could replace it with the regular alpha character and apply an italic font style? Or install a mathematical font that supports this character.

Update: the problem was solved by installing Cambria Math font on Mac.
