R devel - Jan 2011 - Windows script editor and locale

Maybe I'm just overlooking something, but I can't figure out how to
set/change the locale of a file loaded into the built-in script editor on
Windows.

The generic issue is that if I make a teaching script on a Mac, save it to a USB
stick, and open it in the script editor in a classroom, then special Danish
characters in the comments come out as two-byte sequences, which are pretty
unsightly. I know that I can convert the file with iconv (or iconv()), but then
I'd have to maintain two copies of the same file for the two operating
systems, if I want the students to access it. Would be nice if there was
something like a set-coding-system to call up via a menu item.

Any pointers?

There is no support for files in alternative encodings in RGui's 
menus: not to source files nor to load into a pager or the script 
editor.  (I believe all of those long predate any support for 
encodings in R.)

Such provision is rather rare on Windows: files are almost everywhere 
assumed to be in the current Windows codepage (or sometimes WinANSI, 
as in the 'Command prompt' terminal) or in so-called Unicode (usually 
UCS-2LE, possibly UTF-16LE, with a BOM).

I think you could equally ask the same question in reverse: AFAICS the 
R.app GUI has no support for Latin-1 nor UCS-2LE files.  At least in 
our UK experience, the proportion of non-Windows users is so low that 
it is those (including this instructor) who expect to adjust.

What might make some sense is for file.edit() to gain a 'fileEncoding' 
argument so this could at least be done from the command-line.
