Is there a tool out there that provides unicode codepoint display? Kind of like a hex editor except the codepoints would be displayed rather than bytes.
to clarify:
I want to be able to display a document (either a file, or paste what's in the clipboard), and have two views of that document at once,
- the original text including unicode characters displayed normally
- a list of codepoints corresponding to those characters
and it should be able to highlight an individual character in both views so I can see what codepoint corresponds to a particular character I'm interested in.
Read-only features would be fine for what I need, but read-write would also be nice.
