Right, one should use UTF-8 (on all platforms) as the locale encoding.
For historical reasons, one can still parse UTF-8 when R is running e.g.
in Latin 1 locale. This is still supported as older Windows systems
don't use UTF-8 as the native encoding, yet.
When R runs in a non-UTF-8 multi-byte locale, it cannot parse UTF-8 R
input files. This is due to how the parser works and supporting that
would require a major rewrite which would not be worth the effort
(instead effort has been spent on supporting UTF-8 as the native
encoding on Windows).
