REVISION SUMMARY
  Simplify first to not have zero terminators suddenly replaced by '-'.
  This makes some screen names a lot more readable since the encoding
  seems always problematic. According to the standard it should be ipm
  437, but even with that code page, many EDIDs seem to produce garbage.
  Local8Bit also doesn't make much sense, so use Latin1 as a good
  compromise and replace everything that's not in range.
