  2. Binary-to-text encoding - Wikipedia

    en.wikipedia.org/wiki/Binary-to-text_encoding

    Files that contain machine-executable code and non-textual data typically contain all 256 possible eight-bit byte values. Many computer programs came to rely on this distinction between seven-bit text and eight-bit binary data, and would not function properly if non-ASCII characters appeared in data that was expected to include only ASCII text ...

  3. Quoted-printable - Wikipedia

    en.wikipedia.org/wiki/Quoted-printable

    Any 8-bit byte value may be encoded with 3 characters: an = followed by two hexadecimal digits (0–9 or A–F) representing the byte's numeric value. For example, an ASCII form feed character (decimal value 12) can be represented by =0C, and an ASCII equal sign (decimal value 61) must be represented by =3D.

  4. Comparison of data-serialization formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_data...

    ^ The primary format is binary, but text and JSON formats are available. [ 8 ] [ 9 ] ^ Means that generic tools/libraries know how to encode, decode, and dereference a reference to another piece of data in the same document.

  5. Comparison of Unicode encodings - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Unicode...

    The tables below list the number of bytes per code point for different Unicode ranges. Any additional comments needed are included in the table. The figures assume that overheads at the start and end of the block of text are negligible. N.B. The tables below list numbers of bytes per code point, not per user visible "character" (or "grapheme ...

  6. UTF-8 - Wikipedia

    en.wikipedia.org/wiki/UTF-8

    It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file.

  7. ASCII - Wikipedia

    en.wikipedia.org/wiki/ASCII

    The use of ASCII format for Network Interchange was described in 1969. [10] That document was formally elevated to an Internet Standard in 2015. [11] Originally based on the (modern) English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart in this article. [12]

  8. Wide character - Wikipedia

    en.wikipedia.org/wiki/Wide_character

    A wide character refers to the size of the datatype in memory. It does not state how each value in a character set is defined. Those values are instead defined using character sets, with UCS and Unicode simply being two common character sets that encode more characters than an 8-bit wide numeric value (255 total) would allow.

  9. Base36 - Wikipedia

    en.wikipedia.org/wiki/Base36

    Base36 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-36 representation.The choice of 36 is convenient in that the digits can be represented using the Arabic numerals 0–9 and the Latin letters A–Z [1] (the ISO basic Latin alphabet).
