I fixed it by added a encodeURIComponent() method:

var topic_url = tid + (req.params.slug ? '/' + req.params.slug : '');
to
var topic_url = tid + (req.params.slug ? '/' + encodeURIComponent(req.params.slug) : '');

platform: win7
browser: IE9

when I using NodeBB with my local lanuage (chinese),I'm trying to write some posts,when the title is some chinese characters, It will cause an URI error in IE9.Such as "%E6%B5%8B%E8%AF%95" which mean "Test".

decodeURIComponent('%E6%B5%8B%E8%AF%95') => 测试

so when using IE9 I can't open any posts which title has chinese character.

warn: Invalid meta tag.[object Object]
{ property: 'keywords', content: '' }
warn: Invalid meta tag.[object Object]
{ name: 'description', content: '' }

with the code:

console.log(tag)```

when I installed in my local vagrant, I got the error.
