Validation Failed(422) found in gitalk

[duval1024]

Here comes the second issues. Please let me fix it if needed this time.

Actual behavior

I use gitalk in Chinese language. And the URI encoding makes the parameter named id pretty long（more than 50 chars）which results in Validation Failed （422）

new Gitalk({
          clientID: '{{ .Site.Params.comment.gitalk.clientId }}',
          clientSecret: '{{ .Site.Params.comment.gitalk.clientSecret }}',
          repo: '{{ .Site.Params.comment.gitalk.repo }}',
          owner: '{{ .Site.Params.comment.gitalk.owner }}',
          admin: ['{{ .Site.Params.comment.gitalk.owner }}'],
          id: '{{ .RelPermalink }}',  // Ensure uniqueness and length less than 50
          ...{{ .Site.Params.comment.gitalk.options | jsonify | safeJS }}
        }).render('gitalk')

How to fix

wrapper {{ .RelPermalink }} by decodeURI function.
