I tried to create a tag on SO that contained a plus character ("+"), but instead two separate tags were passed in. How can I create a tag that contains "+"?

b-tree is the tag for both, b-tree and b+ tree. You do not need an extra tag for it. You explain in your question that it is a b+ tree, that's sufficient.
No-one clicking with "oh, a b-tree question, I can answer this!" in mind will be scared away with "Aaaah, b+! The evil master! Run, run!" after reading the question text.
There are already several questions which do exactly that (using b-tree for b+ trees, not scaring their readers away).

I actually want a + for use in b+tree, because b-tree is something different
Here's a workaround:
b-plus-tree

this is what I recommend, if the distinction is so important. we don't allow plus in the middle of tags. Jun 7, 2010 at 8:59
You can't create tags with a plus in the middle, because .. well, just look:
http://example.com/questions/tagged/b+tree
is that questions tagged [b] and [tree]?
Incidentally, that's why when any tag contains a plus (we only allow it at the end) you must (and our system does) delimit tags in URLs with a space.

If you're creating new tags, you're probably doing something wrong. 99% of the time or more you should be using existing tags. It's extremely rare to have a question that covers a completely new topic area.

b+treewhen there's already ab-tree(and a few/several other tags along those lines), then people will be confused and use the wrong tag, or use both tags. Yes, you could put the information in the tag excerpt, but people commonly don't read those.
