[R] How to know if a bug was recognised

You have already been sent an answer.  It is a bug in your copy of 
Windows, and it will be worked around in the current version of R-patched. 
From the CHANGES file:

   R 2.0.1 patched

   We work around reported bugs in Windows XP as to which characters are
   printable by attempting to print all non-control characters when using

Note: no one else has reported a problem on 98SE, despite this having been 
the behaviour of R for three months, and it seemed only XP SP2 was 
affected.  Indeed, no one reported the problem for 2.0.0 at all, including 
all the alpha and beta test versions (except for Chinese where the 
characters are invalid and so the behaviour was correct), and so the 
workaround did not make 2.0.1.

BTW, your expectation that an email you sent at the weekend will be 
answered by Tuesday is completely unreasonable.  R is a volunteer project, 
and the developers do have other commitments (and occasionally make 
attempts to have a life).

[You could have read the archives of the R mailing lists to find that this 
was a known issue that had already been addressed.]
