[R] problem with source(), parse() and "french" colnames

[Prof Brian Ripley]

I am unable to reproduce this.  Note that source() makes use of 
options("encoding"), and that should be

> options("encoding")
$encoding
[1] "native.enc"

I do get a problem with e.g. source("foo.R", encoding="ASCII")

If that is not the problem, please produce a small reproducible example 
that fails when run with Rterm.exe --vanilla. As the footer of every 
message says:

(and that asks you not to send HTML mail).
