Lesson plan
Unicode input
character mapping tool shown displaying a subset of the Unicode Mathematical Operators|alt= Unicode input is a method to encode specific characters that are not directly available on a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence or a 'chord' of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive screen. In contrast to ASCII's 96 element character set (which it contains), Unicode encodes hundreds of thousands of graphemes (characters) from almost all of the world's written languages as well as many other signs and symbols. A comprehensive Unicode input system must provide for a large repertoire of characters, ideally all valid Unicode code points. This is different from a keyboard layout which defines keys and their combinations only for a limited number of characters appropriate for a certain locale. Nevertheless, the latter technique (particularly if an "extended" setting is used) is often adequate to satisfy the needs of most users, most of the time.
