No distro implements what we have in LFS-6.2. Also, the text on the
kernel page is now slightly wrong because, unlike previous versions,
linux-2.6.17 does attempt to avoid producing invalid UTF-8 sequences
(this doesn't mean "always produces correct characters"). So let's stay
with what upstream has tested, and apply the following patch to the book
(it does introduce regressions in functionality, but we are still not
worse than anyone else).
