Describe the bug
I’m building a project in Persian, which is a non-English language that uses a non-Latin alphabet. Today I noticed that pages with non-Latin characters in their route paths — like the example below:
import { createFileRoute } from '@tanstack/react-router'
export const Route = createFileRoute('/تست')({
component: RouteComponent,
})
function RouteComponent() {
return <div>Hello "/تست"!</div>
}are not being rendered.
And in the browser console, only this code/message is shown:
<html><head></head><body></body></html>Your Example Website or App
https://github.com/Mrahmani71/test-tanstack-start
Steps to Reproduce the Bug or Issue
After installing the packages and running the project, go to the following link — you’ll see that the page doesn’t render.
http://localhost:3000/%D8%AA%D8%B3%D8%AA
Expected behavior
I expected this page to render just like other pages with Latin characters and display its content correctly.
