But not in some other locale encodings on Windows (e.g. CP-1251), nor
in some single-byte locale encodings on *nix-like systems (e.g.
ru_RU.KOI8-R), which are admittedly used much rarer nowadays than on
Windows. Unless I'm mistaken, the "\u2206t" in your example needs to
become a symbol, and symbols are always translated into the locale
encoding [1] [2].

I would expect this warning to be a problem for CRAN, but I'm just
another package developer, so I could be wrong.
