[PATCH 1/1] oleaut32/tests: Fix test failing on UTF-8 locale.

[Eric Pouech]

From: Eric Pouech

Method decriptor's strings are internally stored in ANSI, and
potentially converted from Unicode using current code page.

Test was expecting loss in Unicode to ANSI conversion.
Adapt test to also support loss-less conversion (that's the case
when code page is UTF-8).
