Escaped non-ASCII characters from source files.

Building libxml2 with VC++ 2008 Express Edition on Windows platform where
the locale is Japanese (or maybe Korean, Chinese or others) fails because
some files generated by test tools in libxml2 contains non-ASCII characters.

This issue is originally reported in OpenOffice.org community (issue 93433)
and a patch is provided by tora, but it has not been applied yet. This
modification is based on the patch and adapted to the current LibreOffice
source.
