More codebox issues

[Mekire]

Just noticed that codebox seems to be parsing things into special characters.

I just entered "open_parenthesis + lowercase_c + close_parenthesis" and it becomes this © regardless of if it is in a code box or not. 

Also it seems impossible to paste code from a code box in another post into a new thread without getting unwanted formatting.

For instance if I take this from another post and try to copy it:

def foo(bar):
    print("Hello")

I get two code boxes each with one line.  Removing formatting doesn't help as then I have a bunch of unwanted code tags to remove.
