ASCII codes represent text in computers, telecommunications equipment, and other devices. ASCII has just 128 code points, of which only 95 are printable characters, which severely limit its scope. The set of available punctuation had significant impact on the syntax of computer languages and text markup.
In computing, a character set is a system of assigning numbers to characters so that text can be represented as a list of numbers (which are then stored, for example, as a file). For example, ASCII assigns the hexidecimal number 41, or 65 in base 10, to "A".
ISO/IEC 8859-13:1998, Information technology — 8-bit single-byte coded graphic character sets — Part 13: Latin alphabet No. 7, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1998. It is informally referred to as Latin-7 or Baltic Rim.
A Unicode character is assigned a unique Name (na). [1] The name is composed of uppercase letters A–Z, digits 0–9, hyphen-minus and space.Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed.
First press the Alt key (and keep it depressed) with your left hand, then press the digit keys 1, 3, 0, in sequence, one by one, in the right-side numeric keypad part of the keyboard, then release the Alt key. Many special characters, however, for example λ (small lambda), cannot be obtained from their decimal code 955 (or 0955), by using it ...
The Basic Latin Unicode block, [3] sometimes informally called C0 Controls and Basic Latin, [4] is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8. The block contains all the letters and control codes of the ASCII encoding.
The character set in the ZX81 was derived from the ZX80 character set.They have mostly the same code points, e.g. for A-Z and 0-9, but the code points are different for the block graphics characters, the symbols ", -, +, *, /, =, >, <, and the BASIC keyword tokens (with many new added).
A bit-paired keyboard is a keyboard where the layout of shifted keys corresponds to columns in the ASCII (1963) table, archetypally the Teletype Model 33 (1963) keyboard. This was later contrasted with a typewriter-paired keyboard , where the layout of shifted keys corresponds to electric typewriter layouts, notably the IBM Selectric (1961).
