Facebook sharing and other stuff

Searching in google (https://www.google.com/search?q=facebook+link+truncating) lead me to some results suggesting lack of encoding as the reason. Here are the first results:

RFC 39... something something is the reference for URL parsing / encoding, using + isn't good, as that is usually encoded as a space, a comma should work, though I don't remember a lot of sites using it. Need to know what sorts of addresses break Facebook, such that we can understand the root cause.

Some stuff I had in notepad that make sense just jotting down.

the link isn't being edited out, just parsed wrong?

encoding the parameter URL doesn't do anything worthwhile.

they seem to discard duplicate parameter names... do parameter key names need to be unique? They also (graphically) ellipse long urls
