"010101010101" doesn't look like what most programmers would consider a
binary string. It looks like a string consisting entirely of printable
characters which just happen to be "0" and "1".
A binary string usually means a string where all possible byte values
are allowed in any combination. I assume that this is what you meant
despite your example.

Memcached treats all strings as binary. The only limitation is the
length (and that is configurable). Up to that length you can store and
retrieve any byte string - memcached doesn't care. Indeed many client
libraries compress values before storing them.

It is possible.
We can't tell you why you get a shorter string back because:
* You didn't tell us what the original string was
* You didn't tell us what the shorter string was
* You didn't tell us what client library you are using
* You didn't tell us what programming language you are using
* You didn't post any code to reproduce the problem
