How to print UTF-8 encoded strings from a C routine to R's output?

Lixin Gong 
Dear R experts,

It seems that Rprintf has to be used to print from a C routine to guarantee
to write to R?s output according to
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Printing.

However if a string is UTF-8 encoded, non-ASCII characters (e.g., the
infinity symbol http://www.fileformat.info/info/unicode/char/221e/index.htm)
are misprinted.
Is this an unsupported feature or is there a workaround for this limitation?

Thanks!

Michael
