You can easily find out what it does by feeding the PHP function a string and look at the result. For example you might put in something like this: 
perl -we 'for (1..127) { print "ABC", chr}; print $/'

Let Wordpress handle that string, and split the result by ABC. Then you have mapping from ASCII to the the corresponding escape sequence.
