Inability to Find Pages
An unlikely scenario, but it's possible that you will get pages with "There is no text in this page" when the page was created in another language from the language of the page containing the link - if the two languages have different content-encodings.
"Fixed" for the next build. Multi-byte processing will be done (if the support is available) regardless of whether the forum language is actually multi-byte. To avoid running into problems, make sure that each language on your forum uses the same content-encoding.
