I'm running the testcase on XP SP3.  I have an idea why it fails for
you.  The eucJP codepage 20932 is not installed by default on US and
other western language systems by default up to Windows 2003.  What you
have to do is, open the "Regional and Language Options" control panel,
go to the "Advanced" tab, scroll the "Code page conversion tables" list
down to the 20932 entry, select it and install it.

This is not necessary anymore startying with Vista, which comes with
almost all important conversion tables preinstalled.
