text encoding

[ksherlock]

LANG=en_US indicates MacRoman.
LANG=en_US.UTF-8 indicates UTF8.

Should support UTF 8 since setting up a new MacRoman terminal and using it exclusively is annoying.

current plan:

• MacRoman is the supported encoding. full stop. MPW Utilities expect it for input and output.
• need to build a custom version of lib edit since it doesn't like non-utf8 8-bit text
• to support utf8, add a macroman utility

usage: macroman executable [flags]

creates a pty and silently handles macroman/utf8 (or other?) encoding
