For more information, see the discussion of comparison functions in Security Considerations:_International Features. Note  For interoperability reasons, the application should prefer the FindNLSStringEx function because Microsoft is migrating toward the use of locale names instead of locale identifiers for new locales. Although FindNLSString supports custom locales, most applications should use FindNLSStringEx for this type of support.
