It's difficult to understand your problem(s) on the basis of this rather sparse description of them. It's much easier to suggest solutions of you show us the code.

For the memory problem, it's almost always possible to avoid running out of memory by only reading manageable chunks of the file at a time. See perlvar and the description for $/. Particularly setting  $/ = \4096; in order to read 4kb at a time with <fh>. Alternatively look at sysread in perlfunc.

For your editing problem, it sounds like your using regex on binary data, but that data is being treated as unicode. Total speculation, that would be clarified by seeing the code, or at least a worked example of the input, method of edit, actual and expected outputs.
