It seems that the pingback mechanism is stymied by unicode characters in URLs. A few days ago I posted this entry:
where I had to us the Unicode character ¹ because I can't use the <sup> tag in a title field.
In the last couple days I posted these:
both of which link back to the first post. They sent all their other pingbacks as expected, but neither has generated a pingback to the first post I mentioned. My only guess is that this has something to do with the Unicode character.
Is this an oversight that might be fixed? If not, can I force a pingback some other way?
The blog I need help with is unapologetic.wordpress.com.
