cp1252 encoding for hawc2.htc_file
hawc2/htc_file.py reads and write htc files with Windows specific encoding cp1252
(other systems can also read these files though). I know there are some htc files going around that contain characters that will fail when reading in utf-8
mode. To avoid weird things like that from happening we should always, without exception, write text files in standard utf-8
format.
But maybe I am overlooking something?
