This has all kinds of uses. If I don't recognize what language I'm looking at, Character Identifier can usually help. If I want to know how some Unicode character was composed (e.g., strikethrough in plain text, h̶o̶w̶ ̶i̶s̶ ̶t̶h̶a̶t̶ ̶p̶o̶s̶s̶i̶b̶l̶e̶?̶), this often helps. If I'm unsure of which character I'm looking at (some characters in some fonts look identical or nearly so), this tells me what it really is.
It would be nice to be able to identify characters in textboxes, though.
Simple but has so many uses. Thanks.
