I can reproduce this on Fedora 7 in that the \u2080 is reproduced as is
and not as a subscript, unlike the other \uXXXX which appear as
subscripted characters,

R version 2.5.1 Patched (2007-08-02 r42389) 
i686-pc-linux-gnu 

locale:
LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C

attached base packages:
[1] "tcltk"     "stats"     "graphics"  "grDevices" "utils"
"datasets" 
[7] "methods"   "base" 

If there is something specific to my Fedora installation that is
different to Peter's that I can ascertain from installed packages/fonts
etc, then let me know and I can provide the output from my laptop.
