I moved my entries from a blog using old style archive links (http://www.my-url.com/archives/xxxxxx.html) to a new blog with updated archive links (http://www.my-new-url.com/yyyy/mm/entry_title_dir.html).

Here's my problem: I've rebuilt all the old entries as redirects pointing to http://www.MYNEWURL.com/ format="%Y">//<$MTEntryTitle dirify="1" trim_to="15"$>.html, but the redirects don't work if there's any punctuation in the post title.

Any ideas as to what I've done wrong and how to fix it?

Thanks!
