All those little symbols just look like typos to me! I think I'm code-blind. In fact I'm still using copy-paste from DrQu+xum's Basic HTML primer to appear clever at work and have been doing for the past 20 years in at least three different jobs.
I confess I copied and pasted it. But I'll take the praise for having to carefully handstuff it with non-breaking spaces to make it line up properly, and the cunning use of the <pre> html tag.
