Odd, but I think not an R issue. I get weirdness in wish too. Try this
% toplevel .a
.a
% label .a.b -text \u03bc\u2080 -font {Roman -10}
.a.b
% pack .a.b
% .a.b configure
{-activebackground
[....]
{-text text Text {} μ₀} {-textvariable textVariable Variable {} {}}
{-underline underline Underline -1 -1} {-width width Width 0 0}
{-wraplength wrapLength WrapLength 0 0}
% .a.b configure -font {Helvetica -12 bold} # the default, now shows \u2080
% .a.b configure -font {Roman -10} # back to Roman, *still* shows \u2080
???!!!
