Having read i18n_characters_in_post_title, I have a page named `St John's` in a file named `St_John__39__s.mdwn`. Regular wikilinks like `\\[[St_John's]]` successfully point to that page. However, if I tag a page with `\[[tag St_John's]]`, that link is shown as pointing to a non-existant page. Modify the tag to read `\[[tag St_John__39__s]]` works around the problem.
