I am sorry, part of the output is garbled, as the email's encoding is different, but the error is hopefully still clear. This is Ubuntu 20.04, yesterday's R devel or R release, in the zh_CN locale. The zh_CN.UTF-8 locale is fine, and it is a much better option, so I am not sure if this is considered to be a bug.
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).
