look at these fools

https://github.com/zear/sabre/blob/master/libzip/bits.c#L99

A missing facet if you're just looking at >>3 is this preceding line:

local unsigned short bi_buf;

So not only is there an assumption of 8-bit bytes, but that unsigned short is at least the size of 2 chars.

But then the fuckers multiply by another 8 for no apparent reason.

THey're working with specific bit-level file formats and playing shitty games with C's exposing of potentially variable machine word widths. What dumbfucks.
