I added a Link via the WP Admin area and realized that it was cut off at 256 characters. The link is rather long at 429 characters. It appears to be encoded in something similar to base64.
I can do some kind of work around, but it would be preferable to be able to use the Links feature in this particular case. The link is inserted within the navigation area of a theme, and it's easier for a client to manage this way.
Would this be a change that could be considered, or would it be silly for WP to support huge links like this?
Worth noting: I altered the wp_links table and changed the data type on link_url from VARCHAR(255) to VARCHAR(1024). This allowed me to insert the huge link, so the DB is the limiting factor here. I'm not keen on changes like this though. In fact, I feel quite dirty now.
