  • Unicode Standard

    A universal character encoding that most modern software programs and communication protocols use to process, store, and exchange textual data. Each character in the Unicode Standard is represented by a unique integer called a code point. Besides encompassing characters from writing systems around the world, the Unicode Standard includes technical symbols, punctuation, and other characters used in written text (e.g., emojis).

    The Unicode Standard is the basis for Internationalized Domain Names.
