Carved in mystic runes upon the very living rock, the last words of Andy

> Yes. The - sign isn't listed in the range (i.e. it would be
> [^0-9.\-]) so it will remove it from the output

In brackets, you only escape the [] characters themselves. Your expression
will allow the \ character in the string.
