I suppose OP can claim "Huh, I don't know, must be a bug in the software I'm using." (there's been cases where MS Word kept deleted text in the Word file, yes I know a CV is usually PDF, but hey, maybe my homebrew PDF generator is buggy!) And I wonder if this argument would fly, e.g. in a court of law: "the information I would like to convey to HR is the one that is readable by human eyes when my CV is rendered by a normal PDF reader (e.g. insert known PDF readers here), anything that is not readable by the human eyes should not be considered part of my CV.".
