 From the Apache 2.2 documentation:

Some Notes

For security reasons, starting with version 2.0.46, non-printable and  
other special characters in %r, %i and %o are escaped using \xhh  
sequences, where hh stands for the hexadecimal representation of the  
raw byte. Exceptions from this rule are " and \, which are escaped by  
prepending a backslash, and all whitespace characters, which are  
written in their C-style notation (\n, \t, etc). In versions prior to  
2.0.46, no escaping was performed on these strings so you had to be  
quite careful when dealing with raw log files.

So, for Apache, at least, what I'm seeing is expected behavior.
