It can, if you tame it appropriately.  (Be sure to disable any input or
output encoding.)  Emacs even has hexl-mode for in-place editing of binary
files.  As far as I know, hexl-mode cannot insert or remove bytes, but
you are probably interested in in-place editing at first.

Perl can be useful too, but you have to be careful not to produce
write-only code. :-)
