Define a range of characters you consider acceptable, and you'll be
able to use regular expressions to remove everything else. For example,
the following expression should remove everything except ASCII digits,
dots, and hyphen-minus:

gsub('[^0-9.-]+', '', dat2)

There is a brief introduction to regular expressions in ?regex and
various online resources such as <https://regex101.com/>.
