It's customary to copy the list with answers, so everyone can benefit 
who may run into the same issue, too.

Those bytes are there for a reason, it's not mad.  It's using wide 
characters, possibly due to Unicode encoding.  If there are special
characters involved (multinational applications or whatever), you'll 
destroy them by killing the null bytes and won't handle the case of that 
high-order byte being something other than zero.

Check out Python's Unicode handling, and character set encode/decode 
features for a robust way to translate the output you're getting.
