Greetings, R-Helpers: I am trying to build a package on WinXP, something that I have done before, but infrequently, and have recently updated both the Rtools and the version of R being used. My test case fails after successfully creating the compiled html files with this error message: . . .

Helpful suggestions would be greatly appreciated.
The \uxxxx sequences are Unicode characters. The xxxx are supposed to
be hexadecimal digits. So you might have something like
cat("\u00B7")
to display a dot. "Invalid" means it's not recognized, or not well-formed.
So what I'd suggest is to search your source code for \u, and see if you
inadvertantly included this for some other purpose. Alternatively, it's
possible something has translated a non-Ascii character into a \uxxxx
sequence; I don't know what might have done that.
If none of that works, you could try reporting on what versions of
everything you're using. You didn't mention that yet. And if they are
all currrent versions (R 2.6.2, Rtools 2.7) then I guess you'll just
have to divide and conquer: cut out half the source code and see if you
still get the error. If so, cut it again, if not, look in the other half.
