I am using the Tweet Web Intent to generate simple “tweet this” buttons. My PHP code looks something like this:
echo https://twitter.com/intent/tweet?text='.urlencode($my_text);
In a few tweets, the plus signs do not get stripped out. In most tweets they do get stripped out. Check this search result (view the “Live” tab). There’s a bunch of correct ones and a bunch of wrong ones, but the wrong ones are in the minority.
They all originate from this page on my site.
Can I do something about this? Or does the fault lie with Twitter?
