/// - For Nextcloud 32 and newer, WCF enforcement depends on the `windowsCompatibleFilenamesEnabled` flag
///  provided by the server capabilities.
/// - For Nextcloud 30 and 31, WCF restrictions are always applied (feature considered enabled).
/// - For versions older than 30, WCF is not supported, and no restrictions are applied.
