pdf is creating squares in text when viewed by colleague on different computer

[marcusg72683803]

I'm creating proofs in InDesign, which looks fine to me, when I check them out. But when viewed by my colleague on another computer the apostrophes are changing into small squares in the text. Screen grabs attached. Any ideas what I might have done wrong creating the pdfs, setting is at (High Quality Print), font?

Its the 'I Do' bit.

Are you using fonts with embedding rights? How are the PDFs being viewed? Have you tried PDF/X-4?

Open the pdf in Acrobat and check its Document Properties (accessed with Command-D on a Mac and Control-D on a PC) Fonts section to confirm that the fonts have been embedded. If the fonts are not embedded then this problem looks like something that I have seen before with different versions of Arial (which this looks like it could be) opening the same file. Certain characters (like quotes) displayed as boxes like this when a different version of this font was used instead of the one that created the file.
