I have someone setting up a document for me on her Mac and i want to assist with some minor text changes like making capital letters and italics. But i am on a PC. I understand that if we both are using open type fonts there should be no major issues. She says her document is in Garamond Pro and doesn't think it's .otf. I was under the impression that Garamond Pro was always an .otf?? If she indeed does have the .ttf version, could she just download the .otf version of this font and apply it to the document or would that cause reflow issues?
