Actually, that's not true. Look at the encoding section of the PwdHash USENIX paper. PwdHash returns an ASCII representation (not a hex or base64 encoded string) of the hashed domain name + master password. PwdHash also applies a number of constraints to the returned hash to ensure that the special characters that it does use are legal at most websites. A typical PwdHash password, with domain name google.com and master password "LetMeIn+123456?" looks like this: 6+LYoE/C0wP8dGPoO Try it yourself at the pwdhash website.
