These do not work in the pdf() device used for R-devel CMD check on CRAN
(and for most others) and so give a check failure with R-devel CMD check
--as-cran or if environment variable R_CHECK_MBCS_CONVERSION_FAILURE
is set to a non-empty value. Note that this stops at the first issue.
NB: the issues will not be seen on a platform whose libiconv does
transliteration -- known are macOS 14 and Alpine Linux. But for example
on macOS 14, missing symbols are silently substituted by ?, which is not
useful.
[The cairo_pdf() and cairo_ps() devices handle fonts differently and can
plot a wider (but platform-dependent) range of Unicode chars. You could
arrange for your examples/tests to use cairo_pdf() if dev.cur() shows
the current device is pdf() and cairo_pdf() finds the glyphs.
None of the graphics devices to which I have access were able to plot
the emojis used by WhatsR.
For superscripts (reporter) another possibility is to use plotmath.
Please correct before 2023-11-14 to safely retain your package on CRAN.
Do study the plots produced: CRAN submissions does not have resources
to do so.
