I'm trying to add some editing symbols to a PDF in Preview on my iMac. I'd like to add an insertion symbol--a caret symbol, an upside-down V). I see in the edit menu an option for emojis & Symbols. I've found a caret symbol there, but it doesn't copy to the PDF. Am I doing something wrong in Preview to use this symbol? Ideally, I'd also like to add a period symbol (small circle with a dot in the middle) and a capital letter symbol (three small, short stacked lines). Any ideas on how to get at least the caret symbol to work?
