Yes, use character sets, e.g. [+] and [-]. If more characters are in a set
along with a hyphen, that hyphen needs to be the first element of the set
so as not to be interpreted as defining a range of characters. So, the
character set containing 0, 9 and hyphen is [-09] or [-90], not [0-9],
which would include all digits between 0 and 9, but not the hyphen.
