Code points and encodings
Unicode assigns an abstract code point such as U+1F99C to a character. UTF-8 represents that code point as one to four bytes for storage or transfer.
Invisible characters
Whitespace is displayed with a quoted escape form, helping reveal tabs, line breaks, and unexpected spacing characters.
Grapheme clusters
Some visible symbols combine multiple code points, including accented sequences, emoji modifiers, and joined emoji. This tool reports code points individually.
