The adding of kindurl= no longer works. Fix needed.

@mrkrndvs I’ve found that if there’s an emoji within any of the metadata sucked into the meta box fields, the filter that sits on these fields to prevent malicious code, can then remove ALL of the data from them when you either save as a draft or try to publish the post.

If you’re finding that it doesn’t seem to work or does so sporadically, you might take a look for things like emoji or other potential unrecognized characters for the URLs you’re trying to use to see if that’s what is causing the bug.
