enscript doesn't support UTF-8

[sascha-wolf]

As the title says.

Since the plugin is heavily dependent on enscript I would like to propose a solution which won't need a huge rewrite but is more of a workaround.

When printing a file with UTF-8 encoding you could issue a warning message and offer to try to encode the file using a different encoding, for example latin1, and then proceed to print. The Sublime API offers methods to change the encoding of a file. Or, if you don't want to do that, at least show a warning if someone tries to print a UTF-8 encoded file.

Right now it just prints gibberish without any prior warning.
