Actually UTF-16 can't encode billions of characters, as it specifically uses a pair of extension/surrogate characters, which encode about 10 bits each, leading to the extra 16 planes. The format for UTF-8 was designed (and could trivially be extended) to support 31 bit code points (with a six byte sequence). It was limited to the current 17-plane scheme by the adoption of UTF-16, which could only address 17 planes (the BMP plus the 16 extra planes implied by the 20-bit number encoded in the surrogate characters).
