Strict Permalinks

Restricts permalink syntax and disables permalink editing after a post is published.

Strict Permalinks does two things:

  1. Restricts the post_name portion of the permalink to alphanumerics and hyphens
  2. Disables permalink editing once a post is published

Like me, you may have been under the impression that post slugs are already restricted to alphanumerics and hyphens. In the current WordPress 2.8.5, a title that includes certain kinds of punctuation (e.g., "smartquotes") will result in URL-encoded characters in the post_name field. Many browsers handle this oddity seamlessly, however this may cause difficulties when integrating with systems expecting a more limited URL syntax.
