Re: Tag characters and in-line graphics (from Tag characters)

"Today the world goes very well with HTML(5) which is now the bext markup language for document (including for inserting embedded images that don’t require any external request”

If I had a large document that reused a particular character thousands of times, would this HTML markup require embedding that character thousands of times, or could I define the character once at the beginning of the sequence, and then refer back to it in a space efficient way?

Part of the reason at least of having any code system rather than just pixels and images is to efficiently and consistently encode data. Unicode has private use ranges of codes. I can see an argument that it would be desirable to be able to send someone text with private use ranges and have the header define some default renderings. I’m not sure that replacing a document of 100,000 characters with 100,000 embedded html5 <img tags is the same thing. It would be inefficient in space. Impossible to process (e.g. find all the instances of a particular character, or sequence), and so forth.

Given that its been agreed that private use ranges are a good thing, and given that we can agree that exchanging data is a good thing, maybe something should bring those two things together. Just a thought.
