MediaWiki's Arabic locale itself by default use Arabic digits but MediaWiki configuration of Arabic Wikipedia do not use that. See this part of Wikipedia servers configurations: https://github.com/wikimedia/operations-mediawiki-config/blob/94324d93a58634a70ad3cc84263e2b901bc8923f/wmf-config/InitialiseSettings.php#L3919 There should be someway for such sites to disable localized numbers WITHOUT disabling it by default.

Well, there is a workaround, using lang="en", but am not sure if this is clean way of that and IMO is just a hack. Was nice if there was a dedicated CSS selector for just controlling numbers localization.

Using lang="en" on the <input> seems like the right way to me. Anyway, the mailing list www-style@w3.org is a better forum to request new CSS properties.

Yeah, I don't see what's wrong with @lang either.

The locale is selected using a BCP lang tag. https://en.wikipedia.org/wiki/IETF_language_tag Is there maybe a more specific tag for Arabic Wikipedia to use than "en"?

Thank you :jwatt. "ar-u-nu-latn" sounds very reasonable to me so I've opened a bug on Wikimedia https://bugzilla.wikimedia.org/show_bug.cgi?id=62725 and am closing this bug.
