I changed it to base64safe (without -), because regexp in interpolateName can be used in many place and I don't want to change it

Let's also use a table to achieve higher entropy, removing characters can create conflicts, i.e. 3ZWmHo0=hPMWE2rZeN_oHB6 and 3ZWmHo0hPMWE2rZe=N_oHB6 will be same after removing characters, this is bad
