I’m using dot to re-create handwritten trees, and there are two little things that would make it better:
- Can I change the text color within a node? (Edit: Yes! with HTML-like labels.)
- I want to add special characters, like schwa and vowels with macrons. (I checked HTML resources, and it doesn’t look like it has encodings for those characters.) Are there codes for special characters besides the three line-breaks? And if so, do I have to choose between special characters and HTML-like labels?
