This was related to encoding changes. It likely appeared Windows-specific because Windows uses a different default encoding than most Linux systems. I believe it is fixed now in R-devel, and it will soon make it into 2.10.1-patched, but it came too late to make it into today's release. I believe PR#14114 was the same issue and is also fixed, but I did less testing of it. I'd appreciate it if those who saw either bug in real code test the patches. They should be in today's tarball of R-devel, and did make it into the Windows binary build of R-devel this morning.
