Arabic and riht to left sites Seo

If we have site on this language, should we make sure that it is displayed from right to left ? Wordpress has this automatic feature when u change the language to arabic it changes the orientation. Is it necessary to do ? Or we can keep from left to right ? How in this case it will affect the SEO ? anyone with expereince in this .
THannk u very much.

You can not change orientation of these languages because they are written right to left.

Changing orientation will make content garbage.

Think of changing orientation of English to right to left and what will you get.

Google knows about this and you do not need to do anything.
