[Vim-l] Using '+' in titles and categories

[John Beckett]

There was a discussion about what to call the category for C++. "C plus
plus" was chosen. Now I'm looking at the tip titles and am wondering about
those that want to use "C++".

Example "STL (Standard Template Library/C++) help via tags":
http://vim.wikia.com/wiki/VimTip931

Why did we decide to use "C plus plus" for the category? Wikipedia seems
able to use "C++". The following article is in Category:C++ due to this
wikitext:
    [[Category:C++]]

http://en.wikipedia.org/wiki/C++

The Wikipedia rules for titles say that '+' can be a problem (and it gives
examples where that occurs). But it seems that "C++" is ok for everyday
usage.

tions)#Plus

Can anyone throw any light on this? Does the wikia.com software handle "+"
differently from Wikipedia?
