Similar, in that it encodes length in the first byte. The differences are:
* It does not require canonicality, it allows multiple encodings of the same value. To make things even more fun, the QUIC spec requires shortest encoding in some uses but not others.
* It uses 2 bits rather than cutting out a range.
* It only encodes values up to 62 bits long.
So, some similarities but also some differences.
