Issue with some utf8 strings and windows

[lepennec]

Hi,

it seems there is an issue with (at least certain utf8) strings in windows:

gridtext::richtext_grob("Любовь")

is producing a warning:

richtext_grob[GRID.richtext_grob.15] 
Warning messages:
1: In text_info(label, fontkey, fontfamily, fontface, fontsize, cache) :
  unable to translate '<U+041B><U+044E><U+0431><U+043E><U+0432><U+044C>RStudioGD12' to native encoding
2: In do.call(gList, grobs) :
  unable to translate '<U+041B><U+044E><U+0431><U+043E><U+0432><U+044C>' to native encoding

My impression is that the issue in text_info is related to the cache. Indeed:

text_info_cache <- new.env(parent = emptyenv())
 text_info_cache[["Любовь"]]

yields

NULL
Warning message:
unable to translate '<U+041B><U+044E><U+0431><U+043E><U+0432><U+044C>' to native encoding 

Note that I did not have this issue under Linux...

Let me know if I can help.

If this is a version of R before 4.2, handling of UTF-8 characters on Windows-R is very bad. The easiest solution would be to upgrade to R 4.2.
