I know about undocumented feature - mb_orig_* functions. And I know
that count()/sizeof() returns the number elements in array, for all
other types it returns 1.
I suggest adding a function, which returns the length of a binary
object in bytes, in MB String module to use that function with
filesystem, network and other functions which handle binary data.
