This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.
In software, a wildcard character is a kind of placeholder represented by a single character, such as an asterisk (*), which can be interpreted as a number of literal characters or an empty string. It is often used in file searches so the full name need not be typed.

With this it is possible to encode 128 (i.e. 2 7) unique values (0–127) to represent the alphabetic, numeric, and punctuation characters commonly used in English, plus a selection of Control characters which do not represent printable characters. For example, the capital letter A is represented in 7 bits as 100 0001 2, 0x41 (101 8) , the ...
4 Line feed is used for "end of line" in text files on Unix / Linux systems. 5 Carriage Return (accompanied by line feed) is used as "end of line" character by Windows, DOS, and most minicomputers other than Unix- / Linux-based systems 6 Control-O has been the "discard output" key. Output is not sent to the terminal, but discarded, until ...
A sequence begins with a greater-than character (">") followed by a description of the sequence (all in a single line). The lines immediately following the description line are the sequence representation, with one letter per amino acid or nucleic acid, and are typically no more than 80 characters in length. For example:
Single-line comments begin with the hash character (#) and continue until the end of the line. Comments spanning more than one line are achieved by inserting a multi-line string (with """ or ''' as the delimiter on each end) that is not used in assignment or otherwise evaluated, but sits in between other statements. Commenting a piece of code:
The difference between superscript/subscript and numerator/denominator glyphs. In many popular computer fonts the Unicode "superscript" and "subscript" characters are actually numerator and denominator glyphs. Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. [1]
