Like this:

digraph g {
  1 -> 2 [label=<Regular<SUB>subscript</SUB>>];
}

What if I got char like "<" or ">" in the label? Who to escape them? – enchanter Jun 27 '14 at 00:31

@enchanter According to the [HTML specification](http://www.w3.org/TR/html4/sgml/entities.html), one can [encode](http://www.html-entities.org/) many special characters. "<" becomes `<` and ">" is `>`. UTF-8 HTML encodings `<` and `>` do also work with Graphviz labels. – Serge Stroobandt Dec 20 '14 at 21:02
