Oh and hash functions won't output symbols or banned chars. They output numbers and you can choose to represent those numbers in whatever mad way that you want, typically as hex, ie. letters and digits.
The length might be a problem but there's nothing to stop you truncating the hash.
The used hashing mechanism is quite weak. If you don't have a long high-entropy master password, it should be feasible for a site-owner to brute-force your master-password based on the site-specific password.
