Is it possible to translate "{cpp}" into "C++" instead of "C+C+"?

I wonder whether it is possible to render "{cpp}" as "C++" instead of "C++" in the generated HTML. Since I am writing a blog about C++, I use it a lot (even in page titles and descriptions) and I am afraid this would hinder Google indexing of my pages. Even Google Style Guide recommends using characters instead of HTML entities if possible (https://google.github.io/styleguide/htmlcssguide.html#Entity_References).
