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?
If you are working in a UTF-8 locale (as on most Unix-like systems), you
should be fine. If not (as is normal on Windows), you'll need to
translate the string to the local encoding. The Writing R Extensions
manual section 6.11 tells you how to do the re-encoding.
