I am migrating a blog from Movable Type 3 to WordPress.

The blog is written in English and Chinese. The URL's of the posts that were made in Chinese came out to something similar to this in Movable Type 3 when they were written:

site.com/2012/06/articles/dispute-resolution/aaeccaacaaeeeaaaaaaaeecaiiii/

The part we are looking at is the /aaeccaacaaeeeaaaaaaaeecaiiii/ part

After I migrated the content to WordPress, WordPress actually recognized the Chinese characters of the topics and inserted them into the database as Chinese:

site.com/2012/06/29/因出资瑕疵引发的公司诉讼-跨国公司在华公司诉/

Does anybody recognize what type of encoding Movable Type is using for the /aaeccaacaaeeeaaaaaaaeecaiiii/ part of the URL? I would like to figure out how to get these mapped to the new WordPress equivelants without having to manually do 301 redirects on 200 posts.
