I placed an Illustrator document into an InDesign document. Some of the text shows up as square symbols. For example: the capital letter "N" is now a square symbol. I am using Illustrator CC 2015 and InDesign CC.
Also, when I export the document as a PDF, those letters are exporting as square symbols.
Thanks for your help in advance.
That means that some of the characters are not available in the font. What font are you using?
I am just using Arial, with a bold setting. So it should be available cause I have used Arial so many times for years.
