You can use _plus_ to translate into a plus character, in both things you say and objects you write in.
this was not written in C++
This wont work as a clickable link as they have already been converted into plusses.
You can do the same with _amp_ if you need an ampersand:
Fish & chips
Fish + chips
Note: you can not re-edit something (like this) as again the characters have already been translated...
The function parse_unput() is what needs fixing if we plan to improve this current situation.
Right now I have bigger fish to fry.. working on daisy-chains and such like.
