[R] Mac-specific encoding bug

[Oliver Keyes]

Hey all,

I've ran into a weird quirk on Mac platforms, which you can read fully
at https://github.com/Ironholds/urltools/issues/70

The long and the short of it is that one specific codepoint - \u04cf -
does not print in a UTF-8-y way by default, except when run through
cat(). Compare, for example:

encodeString("\u04cf")

and:

encodeString("\u044D")

Kevin Ushey was kind enough to bring his expertise, and found that it
may be a locale-specific problem as well as a Mac-specific problem,
because 'sourcetools' shows that there's no locale information for the
character. But this only appears in R - Python has it display
perfectly - so I'm kind of at a loss. Does anyone know what's going
on?

Best,

Oliver
