Comment (by ryandesign):

 No further changes have been made. I had not considered that encoding.h
 might include other icu headers. I'm not certain how many of the headers
 we would have to modify with the absolute path to make this work. I'm not
 sure if going to the trouble of figuring that out and then doing it is
 worthwhile.
