WordPress in Arabic/Hindi/Chinese/Persian

I have a website in wordpress, and I wanted to post some things in other languages that do not use the Latin alphabet like Persian, Arabic, Chinese and Hindi to increase my audience.

But when I do this, the post looks like:
“404 Not Found

Sorry, but the page you are looking for can not be found.
Perhaps you are here beacause the page no longer exists or never exists, or you love 404 page.
Please try searching can help or return to homepage.”

How can I resolve this? (Detail: I wanted to keep the URL in the language I want – Persian, Arabic, Chinese – and not the one that uses Latin alphabet).
