I am using EasyDiscuss to post via email to the forum. The posts are parsed and created correctly when the titles are in English. However, when there are no English characters, the posts are created but without the post alias. So a user can see the post, but the link points to the same page, without the additional path in the URL, so the post is not viewable.
The problem is fixed when an admin user edits the post and saves it, a post alias is automatically created.
The problem doesn't occur if one precedes the Chinese characters with some English characters.
