The German standard DIN 66003, also known as Code page 1011 (CCSID 1011; abbreviated CP1011) by IBM, [1] [2] Code page 20106 (abbreviated CP20106) by Microsoft [3] and D7DEC by Oracle, [4] is a modification of 7-bit ASCII with adaptations for the German language, replacing certain symbol characters with umlauts and the eszett.
A companion Teletype Model 32 used the older, established five-bit Baudot code. [5] Because of its low price and ASCII compatibility, the Model 33 was widely used with early minicomputers , and the large quantity of the teleprinter sold strongly influenced several de facto standards that developed during the 1960s and 1970s.

ISO/IEC 646 is a set of ISO/IEC standards, described as Information technology — ISO 7-bit coded character set for information interchange, and developed in cooperation with ASCII at least since 1964. [1] [2] Since its first edition in 1967 [3] it has specified a 7-bit character code from which several national standards are derived.
Early symbols assigned to the 32 control characters, space and delete characters. (ISO 2047, MIL-STD-188-100, 1972) ISO 2047 (Information processing – Graphical representations for the control characters of the 7-bit coded character set) is a standard for graphical representation of the control characters for debugging purposes, such as may be found in the character generator of a computer ...
The machine generated the appropriate Morse code point from the key press. An entirely new type of code was developed by Émile Baudot, patented in 1874. The Baudot code was a 5-bit binary code, with the bits sent serially. Having a fixed length code greatly simplified the machine design.
ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.
Seven-bit ASCII improved over prior five- and six-bit codes. Of the 2 7 =128 codes, 33 were used for controls, and 95 carefully selected printable characters (94 glyphs and one space), which include the English alphabet (uppercase and lowercase), digits, and 31 punctuation marks and symbols: all of the symbols on a standard US typewriter plus a ...
