Someone just needs to black and white that, throw it in a font program, clean it up, bam, right?
Yeah, I agree that it is the best one.
Slightly off topic, what is needed is some kind of standard way of distributing new fonts.
For example, to register a new character, you would register a domain name at name-of-new-symbol.fnt. This would be a high resolution or vector graphics image of the character.
When a browser or text editor hits an unknown symbol, it could download it and use that. Popular symbols would eventually make it into standard fonts.
To add a symbol to a document you are typing, you would use ALT+name-of-new-symbol and it would add it if available, or download it if not already available.
This could work for all the old symbols too. ALT+d-o-l-l-a-r would give the $ symbol. It would be like a DNS for fonts
. You wouldn't have to remember the unicode numbers. It would make files larger though if you used a lot of non-standard characters.
All it would take it one unicode symbol which means non-standard character.
