How to generate URLs in Asian languages?

I developed a micro SaaS tool. With this tool, people can add things. And it gives titles to the things they add. When you give a title, this title turns into a URL with a permalink.
For example: "You're Welcome" => "your-welcome"

But when Asian languages are involved, the system explodes.

For example: "这是一个例子。" => "这是一个例子。"

The website does not understand this and takes it to the error page. Call it "Zhè shì yīgè lìzi." If I could print it like this maybe it would work, but I searched and couldn't.

I tried with URLEncode/decode, still didn't work.

Maybe you know. If there are Asian entrepreneurs among us or people who have worked in that field, can it help?

Thank you.
