[Tutor] binary data as string?

Personal preference, I don't like modifying original 
data and since shifting is destructive (you lose the 
bits) you need to take a copy of the data before 
modifying it.

In this case we were discussing characters so 8 bits 
is probably right (assuming UTF8 encoding).
The approach is general however, you just change the 
mask value to whatever size you need...
