The 95 isprint codes 32 to 126 are known as the ASCII printable characters. Some older and today uncommon formats include BOO, BTOA , and USR encoding. Most of these encodings generate text containing only a subset of all ASCII printable characters: for example, the base64 encoding generates text that only contains upper case and lower case ...
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.
The selection of graphic characters has some internal logic: Table rows 0 and 1, codes 0 to 31 (00 hex to 1F hex), are assorted dingbats (complementary and decorative characters). The isolated character 127 (7F hex) also belongs to this group. Table rows 2 to 7, codes 32 to 126 (20 hex to 7E hex), are the standard ASCII printable characters.
All printable ASCII characters (decimal values between 33 and 126) may be represented by themselves, except = (decimal 61, hexadecimal 3D, therefore =3D). ASCII tab and space characters , decimal values 9 and 32, may be represented by themselves, except if these characters would appear at the end of the encoded line.
Characters outside of the printable ASCII range (32 to 126) usually appear incorrectly. This presents few problems for English-speaking users, but other languages regularly—in some cases, always—require characters outside that range.
95 characters; the 52 alphabet characters belong to the Latin script. The remaining 43 belong to the common script. The 33 characters classified as ASCII Punctuation & Symbols are also sometimes referred to as ASCII special characters. Often only these characters (and not other Unicode punctuation) are what is meant when an organization says a ...
On an 8-bit clean serial link, ASCII can be expanded to support a total of 256 characters. In this case, instead of replacing the characters in the original printable characters range from 32 to 127, new characters are added in the 128 to 255 range. This offers enough room for a single character set to include all the variety of characters used ...
Control Characters: (see File:US ASCII Control Character Symbols.png) Deutsch: US-ASCII Kodierungstabelle (1967). Die ursprüngliche Notation war 4/11 (Spalte/Zeile) für "K", da die Spalten zu je 16 Zeichen (untere 4 Bit) Gruppen darstellen.
