Windows-1256
Windows-1256 is a code page used under Microsoft Windows to write Arabic and other languages that use Arabic script, such as Persian and Urdu. This code page is ''neither'' compatible with ISO-8859-6 nor the MacArabic encoding. Windows-1256 encodes every ''abstract'' single letter of the basic Arabic alphabet, not every concrete visual form of isolated, initial, medial, final or ligatured letter shape variants (i.e. it encodes characters, not glyphs). The Arabic letters in the C0-FF range are in Arabic alphabetic order, but some Latin characters are interspersed among them. These are some Windows-1252 Latin characters used for French, since this European language has some historic relevance in former French colonies in North Africa such as Morocco and Algeria. This allowed French and Arabic text to be intermixed when using Windows 1256 without any need for code-page switching (however, upper-case letters with diacritics were not included). IBM uses code page 1256 (CCSID 12 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

ISO-8859-6
ISO/IEC 8859-6:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 6: Latin/Arabic alphabet'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as Latin/Arabic. It was designed to cover Arabic. Only nominal letters are encoded, no preshaped forms of the letters, so shaping processing is required for display. It does not include the extra letters needed to write most Arabic-script languages other than Arabic itself (such as Persian, Urdu, etc.). ISO-8859-6 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. The text is in logical order, so BiDi processing is required for display. Nominally ISO-8859-6 (code page 28596) is for "visual order", and ISO-8859-6-I (code page 38596) is for logical order. But in practice, and required for HTML and XML documents, ISO-8859-6 also stands for l ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Windows-125x
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used. There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages. (ANSI is the American National Standards Institute.) Code pages in both of these groups are extended ASCII code pages. Additional code pages are supported by standard Windows conversion routines, but not used as either type of system code page. ANSI code page ANSI code pages (officially called "Windows code pages" after Microsoft accepted the former term being a misnomer ) are used for native non-Unicode (say, byte oriented) applications using a graphical user interf ...

Code Page
In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte. (In some contexts these terms are used more precisely; see .) The term "code page" originated from IBM's EBCDIC-based mainframe systems, but Microsoft, SAP, and Oracle Corporation are among the vendors that use this term. The majority of vendors identify their own character sets by a name. In the case when there is a plethora of character sets (like in IBM), identifying character sets through a number is a convenient way to distinguish them. Originally, the code page numbers referred to the ''page'' numbers in the IBM standard character set manual, a condition which has not held for a long time. Vendors that use a code page system allocate their own code page number to a character encoding, even if it is better known by another name; for example, U ...

CCSID
A CCSID (coded character set identifier) is a 16-bit number that represents a particular encoding of a specific code page. For example, Unicode is a code page that has several encoding (so called "transformation") forms, like UTF-8, UTF-16 and UTF-32, but which may or may not actually be accompanied by a CCSID number to indicate that this encoding is being used. Difference between a code page and a CCSID The terms code page and CCSID are often used interchangeably, even though they are not synonymous. A code page may be only part of what makes up a CCSID. The following definitions from IBM help to illustrate this point: * A glyph is the actual physical pattern of pixels or ink that shows up on a display or printout. * A character is a concept that covers all glyphs associated with a certain symbol. For instance, "F", "F", "''F''", "", "", and "" are all different glyphs, but use the same character. The various modifiers (bold, italic, underline, color, and font) do not change the ...

Enquiry Character
In computer communications, enquiry is a transmission-control character that requests a response from the receiving station with which a connection has been set up. It represents a signal intended to trigger a response at the receiving end, to see whether it is still present. The response, an answer-back code to the terminal that transmitted the WRU (who are you) signal, may include station identification, the type of equipment in service, and the status of the remote station. Some teleprinters had a "programmable" drum, which could hold a 20- or 22-character message. The message was encoded on the drum by breaking tabs off the drum. This sequence could be transmitted upon receipt of an enquiry signal, if enabled, or by pressing the "Here is" key on the keyboard. The 5-bit ITA2 has an enquiry character, as do the later ASCII and EBCDIC. In the 1960s, DEC routinely disabled the answerback feature on Teletype Model 33 terminals because it interfered with the use of the pape ...

End Of Text
The End-of-Text character (ETX) is a control character used to inform the receiving computer that the end of a record has been reached. This may or may not be an indication that all of the data in a record have been received. In ASCII and in EBCDIC, ETX is code point 0x03, often displayed as {{mono, ^C). It is often used as a "break" character (Control-C) to interrupt a program or process. In TOPS-20, it was used to gain the system's attention before logging in. It is often used in conjunction with Start of Text (STX) and Data Link Escape (DLE), e.g., to distinguish frames in the Data link layer. mIRC uses ETX as the color character escape character.

Start Of Text
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent non-printable character, additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the range 00hexadecimal, HEX–1FHEX and the default C0 set was originally defined in ISO 646 (ASCII). C1 codes are the range 80HEX–9FHEX and the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). The ISO/IEC 2022 system of specifying control and graphic characters allows other C0 and C1 sets to be available for specialized applications, but they are rarely used. C0 controls ASCII defined 32 control characters, plus a necessary extra character for the DEL character, 7FHEX or 01111111BIN (needed to punch out all the holes on a paper tape and erase it). This large number of codes ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Null Character
The null character (also null terminator) is a control character with the value zero. It is present in many character sets, including those defined by the Baudot and ITA2 codes, ISO/IEC 646 (or ASCII), the C0 control code, the Universal Coded Character Set (or Unicode), and EBCDIC. It is available in nearly all mainstream programming languages. It is often abbreviated as NUL (or NULL, though in some contexts that term is used for the null pointer). In 8-bit codes, it is known as a null byte. The original meaning of this character was like NOP—when sent to a printer or a terminal, it has no effect (some terminals, however, incorrectly display it as space). When electromechanical teleprinters were used as computer output devices, one or more null characters were sent at the end of each printed line to allow time for the mechanism to return to the first printing position on the next line. On punched tape, the character is represented with no holes at all, so a new unpunched ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Perso-Arabic Script
The Persian alphabet ( fa, الفبای فارسی, Alefbâye Fârsi) is a writing system that is a version of the Arabic script used for the Persian language spoken in Iran ( Western Persian) and Afghanistan (Dari Persian) since the 7th century after the Muslim conquest of Persia. The Persian dialect spoken in Tajikistan (Tajiki Persian) is written in the Tajik alphabet, a modified version of the Cyrillic alphabet which has been in use since the Soviet era. The Persian alphabet is directly derived and developed from the Arabic alphabet. After the Muslim conquest of Persia and the fall of the Sasanian Empire in the 7th century, Arabic became the language of government and especially religion in Persia for two centuries. The replacement of the Pahlavi scripts with the Persian alphabet to write the Persian language was done by the Saffarid dynasty and Samanid dynasty in 9th-century Greater Khorasan. The script is mostly but not exclusively right-to-left; mathematical expressi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
