In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
The control code ranges 0x00–0x1F ("C0") and 0x7F originate from the 1967 edition of US-ASCII.The standard ISO/IEC 2022 (ECMA-35) defines extension methods for ASCII, including a secondary "C1" range of 8-bit control codes from 0x80 to 0x9F, equivalent to 7-bit sequences of ESC with the bytes 0x40 through 0x5F.
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.
There are five possible reasons to assign an alias name to a code point. [1] A character can have multiple aliases: for example U+0008 <control-0008> has control alias BACKSPACE and abbreviation alias BS. 1. Abbreviation Commonly occurring abbreviations (or acronyms) for control codes, format characters, spaces, and variation selectors.
All entries in the ASCII table below code 32 10 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text. The code 127 10 is also a control character. [1] [2] Extended ASCII sets defined by ISO 8859 added the codes 128 10 through 159 10 as control characters. This was primarily done so that if ...
In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
