Question about kerning
I received a proof for my first print book and overall, it looks great. However, as I'm going through page by page, I've noticed issues with certain letters. Every capital W, Q and K have a rectangular box with an "x" in its place. The same for the letter combination "ft" as in swiftly, after, often, etc. This also occured on a lower case b, h and capital D when prefaced by a single quotation mark.
The document was typed in Open Office, Garamond 11 pt and converted to a PDF. I checked the manuscript and noticed that kerning was not turned on. Is the lack of kerning causing the problem? I'd appreciate any feedback.
