    No, I just chose that in my script to show it suppoorted str functionality 
for example, .encode('utf-8'), it is not otherwise related to estr.

I should post the script.

You pass in a function that does the escaping.

By letting the caller set the escaping rules via passed function, estr does not 
have to know anything about escaping, and is much simpler.  Also the caller 
could its own escaping rules.
