chinese characters in url break snapshot

[brandonmp]

One of the routes I have to render has a few chinese chars in it: .../some-route-华安杰/

When snapshot's going thru my routes, it throws on this one with the error below. removing the characters from the path fixes it right up.

/home/bmp/code/admitbrain/node_modules/react-snapshot/lib/snapshot.js:41
        window.react_snapshot_render = function (element, state, rootComponent) {
                                     ^

What is expected behaviour here? I'm able to get this file structure some-route-%E5%8D%8E%E5%AE%89%E6%9D%B0/index.html
