DocBook XSL processing on localized OSes

[Louis Amdur <LAmdur@symantec.com>]

This might be slightly off-topic for
the list, but here goes. I'm deploying a DocBook build system to users
who are using localized versions of Windows XP. Some but not all of these
users--specifically, those who are using XP localized for Simplified Chinese
and Korean (note: Not the language pack, but the full-blown OS) are having
Saxon problems when they attempt to process some of our DocBook content.
The problem occurs when Saxon encounters certain multi-byte UTF-8 characters
(the exact problem characters change per language). On Korean, for example,
Saxon hoses whenever it encounters ’
(right single quotation mark) and throws an error message complaining that
the file is not a valid UTF-8 file. The file actually uses the hex value
e28099 for this, and does not pose a problem for me when I process it on
my US OS based machine. My hypothesis is that there is some JRE issue on
certain OSes, but a concerted Google search has not been fruitful. Or,
perhaps, there is a Windows reg setting that differs per locale. Has anyone
encountered this issue?
