Filter name doesn't support unicode character in url

I share the dashboard with specified filter value like this: http://192.168.1.9:3000/dashboard/19?first_filter=aaa&second_filter=bbb

That’s pretty convenience. Unfortunately, if the filter name is unicode character, such as Chinese, then the url turns to:
http://192.168.1.9:3000/dashboard/19?____=aaa&___=bbb

If the filter name has 3 characters, then I get 3 underscores. If I have two filters that have same length, then I get error, metabase cannot distinguish them.

Hi @chen2liang4 There’s an issue open on it:

Thanks, well, it seems that I’ll have to take your suggestion adding an ascii letter to avoid this issue.
