[Rd] (PR#13195) Can't open files containing russian letters in path

[Prof Brian Ripley]

Thanks, I have found the problem.  It is *far* less extensive than you 
claimed, affecting only a couple of menu items.

The problem is the C-level function consolecmd, which was passing Unicode 
characters to storekey.  That used to be correct, but the changes made by 
the Japanese to incorporate their IME had inter alia broken consolecmd in 
non-Latin-1 single byte locales.

This looks like the explanation for the vague problem reported with the 
script editor, which uses consolecmd to submit commands (whereas the pager 
does not).

Note that those file choice dialog boxes are only intended to work in the 
native encoding, so you can only choose a file name in Russian in a 
Russian version of Windows.  That made tracking this down more than a 
little tedious.
