What it does

This policy setting allows words that contain diacritic characters to be treated as separate words. If you enable this policy setting, words that only differ in diacritics are treated as different words. If you disable this policy setting, words with diacritics and words without diacritics are treated as identical words. This policy setting is not configured by default. If you do not configure this policy setting, the local setting, configured through Control Panel, will be used. Note: By default, the Control Panel setting is set to treat words that differ only because of diacritics as the same word.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
