Internal Link don't support Chinese language

[wpchina]

The Internal Link in WordPress 3.1 do help to SEO. It is a great tool to webmasters. While the feature don't support Chinese or other non-English characters. I hope this issue can be fixed in 3.1 final release.

What is the problem in detail here?

I've asked the same question at ​http://wordpress.org/support/topic/internal-link-dont-support-chinese-language and I really don't have a clue what the bug is.

Perhaps we're not properly encoding the search?

Can't reproduce either. What are the exact steps?

1.just you upload files of chinese file name and it will can't work.

2.when your the post tile name is chinese. then the chinese url can't work.

And what the exact file name or post title should look like? Please give some examples.

I'm asking for some real examples because I've already tested Internal Linking with “Hello World” translated to Chinese (via Google Translate) and it seemed to work fine.

What does that have to do with internal linking?

what is do you mean? I am using IIS6.0 PHP5.3.4 FASICGI MODE, just I upload chinese file,but it isn't show.

and ​http://www.xiaoyuxa.com/tag/远端控制 chinese url cant open address as well.

As for the slug, it works fine on Apache, so it might be an IIS configuration issue.

As for the file name, it doesn't work on Windows indeed. Looks like a duplicate of #15955.

As for Internal Linking, the ticket description might be inaccurate from the start.

it should not IIS issue, I have try use unix hosting, chinese URL not work.

liuxyon, please explain in more than one/two sentences what the problem with the internal linking is about.

maybe I find upload chinese file name, it isn't download reason.

Because when I upload chinese name file via wordpress admin control after, then the file name be force change other encode file name. maybe is utf-8?

such as:

The real chinese file name is: 完美GPS信息_Ulysee Gizmos_1.5.2.rar

upload via WP after file name change to:
瀹岀編GPS淇℃伅_Ulysee-Gizmos_1.5.2.rar
