Subject: [PATCH 3/3] mxvmem: make reading files more robust

Reading logfiles containing 'strange' bytes, would yield
errors like:

  "UnicodeDecodeError: 'utf-8' codec can't decode byte
   0xb3 in position 3221: invalid start byte"

Either switch to binary input, or escape the characters
in question. Here the latter was choosen.
