Tornado url regex unicode chars

I have a tornado application, where the url is something like

https://example.com/my/path/❤

In tornado I have 

handlers = [
        (r'/my/path/❤$', MyHandler),
]

but it is not matching with the path.

I tried tornado.escape.utf8() and tornado.escape.url_escape() with no luck.

If I replace %E2%9D%A4 which is encoded string of ❤ then it works is it possible to make it work without replacing it to encoded string?

No, tornado's routing engine currently works on the encoded form of the urls, so it is impractical to use non-ascii characters in routes. (They work fine if captured as a variable part of the path, so r'/my/path/(.*)' would correctly capture ❤ and pass it as the first argument to the handler).

Handling unicode routes is a longstanding feature request, but it is difficult to solve correctly because of the complexity of the rules defined in RFC 3987.
