HTML Punctuation Code

I know there's a more descriptive term for what I'm talking about. (What is it?)

More specific HTML punctuation code:

‘ = ‘ = opening single quote
’ = ’ = closing single quote (or an apostrophe)

“ = “ = opening double quote
” = ” = closing double quote

′ = ′ = single prime (not in HTML 4.01)
″ = ″ = double prime (not in HTML 4.01)

– = – = en dash (shorter)
— = — = em dash (longer)

… = … = ellipsis
