Thank you, Dirk for raising the issue, providing the nice summary,
and again to Ivan for his patches and Duncan for testing and comments

I've checked the first of Ivan's patches -- IIRC the one Dirk
now also is going to patch the Debian/Ubuntu/... R-base packages with.
The code is nice, short (but not too short), partly self explainable,
and it also works fine under the Fedora_32--current version of

For this reason I've committed to R (the trunk, i.e., R-devel,
for R 4.1.0 in a month or so)  in svn rev 80110.

However we definitely want a stable R 4.0.5 with basically only
a bug fix of the character/UTF-8/.. problem so R 4.0.x itself
will surely not get such a patch.

Best regards,
