[420] nuxt generate folder can't find for non english params ( folder urlencode )

I have a problem when I use generate with Chinese params .

I define some params with Chinese language . It work ok on node.js server , but when I generate static website with routeParams config in nuxt.config.js

generate: {
    routeParams: {
      '/post/:slug': [
        { slug: 'my-first-post' },
        { slug: '我的第一篇文章' }
      ]
    }
  },

static website will show 404 when I refresh at Chinese slug page

I open dist folder , I seen the Chinese params parse a url encode format so I can't access that page , so I manually modify that folder back to Chinese . /post/%E6%88%91%E7%9A%84%E7%AC%AC%E4%B8%80%E7%AF%87%E6%96%87%E7%AB%A0/index.html to /post/我的第一篇文章/index.html It works !

is should generate disabled url encode ? or need a option to fix this ? now , we avoid use Chinese in params , but some customer need use Chinese url ... hope can fix it .

thanks .
