Example result

The first eight bytes carry seven payload bits each. A ninth byte, when needed, carries eight bits. This is not LEB128 or ZigZag.

128 encodes as 81 00. The maximum unsigned 64-bit value uses nine FF bytes.

Accepts unsigned bit patterns through 2⁶⁴−1. Signed database fields may interpret the same bits differently.
