The wiki name "一千零一夜" is not well-formed. Rules for wiki page names:

• Must not begin or end with a space.
• Must not contain any control characters, including tab or newline.
• Must not have two or more spaces in a row internally.
• Must be between 3 and 100 characters in length.

At the same time if I write wiki using non-ASCII character, and then edit it.All non-ASCII character escape with &#+code,that's not the original character edited.

you can see the later from the sandbox's last item.

This is probably also what cc6557cfc5 relates to.

This issue mainly focuses on how to treat the c character type,either char or unsigned char. In function 'wiki_name_is_wellformed', I convert the parameter to unsigned char before comparing, then the wiki name goes fine.

And the variable 'c' in function 'EncodeHttp' is the same issue.
