Deficiencies of ASCII

ASCII is notoriously U.S.centric and did not provide for common Western European symbols such as the British £ symbol, accented letters (e.g. ñ, é, ü), or even the ¢ symbol. In addition, it is a 7-bit code restricted to 128 (27) characters, which is too few characters for the many languages which use accents in their spelling.

However, ASCII has been the default standard since its inception, and is an encoding standard available to almost all modern computers all over the world.
