In RGui you can print the string, because RGui is a Windows Unicode
application (uses UTF16-LE and bypasses the C runtime for strings). But
it is just the gui, R itself (and hence also packages) use the current
native encoding as defined by the C runtime. RGui will make sure R gets
the string in UTF-8, but as soon as you do anything even slightly
non-trivial, which includes formatting, the string will be converted to
the current native encoding. Some R functions allow you to do certain
things in UTF-8 without conversion to native encoding, you'd have to
read very carefully the documentation for each function - but for
practical use, you either need to live with the misinterpretation of
some characters, or use Windows in the locale where your characters can
be represented (e.g. Chinese locale when working with Chinese strings),
or use Linux/maOS. On Linux/macOS the current native encoding can be
UTF-8, so there is no problem. On Windows, with the current toolchain
based on mingw, this is not possible.
