Log:
[ADVAPI32]: Don't directly redirect IsTextUnicode to RtlIsTextUnicode, but use a
helper function, so that the return value is correctly set to TRUE or FALSE. Indeed the
former function returns a BOOL (long) while the latter returns a BOOLEAN (byte), and the
high bytes in the return value could not be correctly set otherwise.

Adapted from a patch by 'andy-123'.
