Unicode input is method to add a specific Unicode character to a computer file; it is a common way to input characters not directly supported by a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive ...
For example, with one byte (8 bits) per character, one can encode 256 possible characters; in order to encode more than 256 characters, the obvious choice would be to use two or more bytes per encoding unit, two bytes (16 bits) would allow 65,536 possible characters, but such a change would break compatibility with existing systems and ...
Most codes are of fixed per-character length or variable-length sequences of fixed-length codes (e.g. Unicode). [4] Common examples of character encoding systems include Morse code, the Baudot code, the American Standard Code for Information Interchange (ASCII) and Unicode. Unicode, a well-defined and extensible encoding system, has replaced ...
On the Common Building Block (CBB) Keyboard for Notebooks, as many 106/109-key keyboards, the Kanji key is located on the Half-width/Full-width key, and needs the key ALT. It is found as a separate key on the IBM PS/55 5576-001 keyboard. On the IBM PS/55 5576-002 keyboard, it is mapped to the left Alt key.
This page lists codes for keyboard characters, the computer code values for common characters, such as the Unicode or HTML entity codes (see below: Table of HTML values"). There are also key chord combinations, such as keying an en dash ('–') by holding ALT+0150 on the numeric keypad of MS Windows computers.

A method to determine what encoding a system is using internally is to ask for the "length" of string containing a single non-BMP character. If the length is 2 then UTF-16 is being used. 4 indicates UTF-8. 3 or 6 may indicate CESU-8. 1 may indicate UTF-32, but more likely indicates the language decodes the string to code points before measuring ...
For example, here are the different “a” characters nested under the standard letter on the iPhone keyboard: It’s not just variants on standard letters you can find hidden in your keyboard.
