Why stop at 5-bit? If you use binary encoding, you could just send it out as a string of 1's and 0's, and you'd get 1120 bits instead of 140 bytes.
Sorry, I'm kidding a bit here. There is no 5-bit characeter set or encoding defined for SMS. (If a 5-bit character set did exist, it could only support 32 characters in the character set which would be very limiting.)
The GSM 7-bit character set is defined in the standards. As long as your message contains only characters in that character set, you can fit 160 characters in a single message.
If you use any characters outside of that character set, the message needs to be sent in Unicode format, which uses 16-bit characters, and can only fit 70 characters in a single message.
You can find a reference to the characters that are in the GSM 7-bit character set in the following discussion thread:
