CSS Customization and numbering system
Fragment of a discussion from Talk:Issues and features/LiquidThreads
It will be better if this option added in core's language supports(I think both CSS3 and Javascript modification is needed for that).
for example users in our wiki must using this ۱۲۳۴... number, but when they used # for making numbered list(before my patch), their result was 1. 2. 3. 4. .... I think this feature is needed for all persian mediawiki wikis.(specialy when result of {{formatnum:123}} is ۱۲۳ in this wikis!)
