Switching between character sets was done using the Shift Out and Shift In characters, or alternatively, on systems supporting 8-bit mode, using the high bit of the character. Before the name "Roman-8" was established for the 8-bit variant in 1983, this was sometimes called "8-bit Roman Extension" or "HP Roman-8 Extension".
The SAS language is a fourth-generation computer programming language used for statistical analysis, created by Anthony James Barr at North Carolina State University. [1] [2] Its primary applications include data mining and machine learning.
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 the high bit was stripped, it would not change a printing character to a C0 control code. This second set is called the C1 set.
Microsoft compressed file in Quantum format, used prior to Windows XP. File can be decompressed using Extract.exe or Expand.exe distributed with earlier versions of Windows. After compression, the last character of the original filename extension is replaced with an underscore, e.g. ‘Setup.exe’ becomes ‘Setup.ex_’. 46 4C 49 46: FLIF: 0 flif
A secondary character map program is accessible in a text field on Windows 10 and Windows 11 computers, using the keyboard shortcut ⊞ Win+., or the 😀 key in Windows 10's virtual touch keyboard, which is mainly used for the purposes of using emoji, but also allows access to a smaller set of special characters.
A legacy of code page 437 is the number combinations used in Windows Alt codes. [6] [7] [8] A DOS user could enter a character by holding down the Alt key and entering the character code on the numpad [6] and many users memorized the numbers needed for CP437 (or for the similar CP850).
Several of the characters are defined to render as a standardized variant if followed by variant indicators. A variant is defined for a zero with a short diagonal stroke: U+0030 DIGIT ZERO, U+FE00 VS1 (0︀). [9] [10] Twelve characters (#, *, and the digits) can be followed by U+FE0E VS15 or U+FE0F VS16 to create emoji variants.
The data portion is encoded like Base32 with the possibility to check and correct up to 6 mistyped characters using the 6-character BCH code at the end, which also checks/corrects the Human Readable Part. The Bech32m variant has a subtle change that makes it more resilient to changes in length. [10] BinHex: Arbitrary: 75%: Perl, C, C (2) MacOS ...
