support for ISO2022 natively. Of course, we've been doing this by default for
years with no ill effect, and all modern operating systems seem to support this

Previously Tidy produced different output based on the compilation target, NOT based on
the file encoding and specified options. Every platform was equal except Mac OS. Now unless
the encoding is specifically set to a Mac file type, all encoding assumptions are the same
across platforms.
