[PATCH 2/2] riched20/tests: Fix the EM_GETSELTEXT tests in Hindi on Windows.

[Francois Gouget]

From: Francois Gouget

On Windows EM_GETSELTEXT fails to convert strings containing \xfffb to
ANSI in the Hindi locale but works in most other locales, including
UTF-8 ones. So check for this issue and adjust the expected results
accordingly.
