Today I Learned that the `=COUNTIF` function in Excel can use "?" as a placeholder for a single character… I had written `=COUNTIF(named_range,"x")+COUNTIF(named_range,"?")` because some of the cells could be an "x" or a question mark, and getting double counting… changed it to `=COUNTIF(named_range,"?")` and worked like a charm… If one of the cells in the range is empty, or has more than one character, it does not count it! And it is also case insensitive.
Just checked in LibreOffice Calc, and Apple Numbers, and it also works there!
