UTF-8 Essay

A sequence to be detected could be “/../” represented in ASCII (a fortiori in UTF-8) by the bytes “2F 2E 2E 2F” in hexadecimal notation.The main characteristic of UTF-8 is that it is backward compatible with the ASCII standard, that is to say that any ASCII character is encoded in UTF-8 as a single byte, identical to the ASCII code.This binary API is supported on all systems where Java has been ported, even those whose operating system does not offer a Unicode text API (support can be done in the host native application or by using the standard libraries supplied with the JVM or other independent native libraries.The consequences are as follows: tripling the volume of data and dividing by three the potential length of the index keys comp...

Text file Essay

In computer science, a text file or plain text file or simple text file is a file whose content represents only a series of characters; it necessarily uses a particular form of character encoding which may be a variant or an extension of the local United States standard, ASCII.It is also due to a complicated history linked to the influence and interests of the United States, an English-speaking country, and to the fact that currently text files are generally ASCII compatible but not limited to these characters.Finally, and more anecdotally, the purpose of a text file can be diverted to contain an image, this is called ASCII art: .In 1971, RFC 265 indicates that a file can be ASCII, core executable, or other.On page 12, the RFC clarifies ...

End of line Essay

In addition, Unicode defines certain properties relating to automatic splitting text on different lines.In order to allow the entry of text evoking end-of-line characters, Unicode defines characters for this use: .In computer science, there is a control character (at least in ASCII and EBCDIC) carriage return (abbreviated CR for English Carriage return).to mention the separators; "Group Separator" (GS 001D base 16) and "Record Separator" (RS 001E base 16) exist since ASCII and are of course present in Unicode.In ASCII, CR is indexed as character 13 in decimal notation and 0D in hexadecimal notation.

Character encoding Essay

On the Internet, UTF-8 and ASCII are the two most popular encodings since 2010.This abandonment will be all the more facilitated as the ISO 10646 and Unicode standards quickly decided to merge their directories and quickly succeeded by producing a major update for Unicode 1.1 (making obsolete version 1.0 of the incompatible Unicode standard, but integrating the UTF-16 encoding form in its standard) and ISO 10646-1 (compatible with ISO 10646, but abandoning the idea of ​​supporting more than 17 plans in the future, and accepting to integrate and standardize UTF-16 ), and by creating procedures allowing the two technical committees to collaborate.One of these most well-known variants is the ISO / IEC 8859-1 code page, developed based on DE...

Unicode Essay

The Unicode standard defines requirements for evaluating the conformity of the implementation of a process (or software) to Unicode.No Unicode typeface can "work" on its own, and full writing support requires support for these in a rendering engine, capable of detecting equivalent encoding forms, searching for contextual forms in text, and select the different glyphs of a font encoded with Unicode, using the included correspondence tables if necessary the police themselves.While ISO / IEC 10646 defines the same character set as Unicode, the difference between ISO / IEC 10646 and Unicode is mainly due to the excess conformance requirement provided by Unicode.Where ASCII uses 7-bit and ISO / IEC 8859-1 8-bit (like most national code pages)...

ISO / IEC 8859-1 Essay

However, even with this one universal ISO / IEC / Unicode character set, there are different binary representations the interpretation of which can be very different if the actual representation is incorrectly determined, a problem that can also lead to to incorrect interpretations, but which can be resolved by integrating here again a metadata on this representation, in particular a byte order mark (often abbreviated BOM) represented by the coded character U + FEFF, placed at the head of the document only for the purpose of determining the binary representation used, but which does not itself then represent any significant coded character in the document.The Unicode standard is generally used when it is necessary to exceed the limits of...

Extended Binary Coded Decimal Interchange Code Essay

The EBCDIC is therefore the result of a much older historical evolution (long developed by IBM in continuity with the old telegraph systems) than the ASCII (more practical to handle in programs) which then replaced it practically everywhere and then gave rise to a standardization in ISO 646. .On EBCDIC systems, the line feed is normally encoded with the C1 control character “NEL” (U + 0085 in Unicode, or 0x25 in all standard EBCDIC variants) and not with the characters of C0 “CR” and / or “LF” control of ISO 646 and ASCII (U + 000D and / or U + 000A, that is to say 0x0D and / or 0x15 in EBCDIC, where these commands have a well-defined and unique function for managing the cursor position on a terminal, or make it possible to distinguish f...

Automatic Encoding Detection And Unicode Conversion Engine Computer Science Essay

Integrating the Unicode viewing support will provide a good opportunity to carry the technology to remote areas if it can be presented in the native language.The Unicode Consortium chose to represent shared ideographs only once because the goal of the Unicode standard was to encode characters independent of the languages that use them.For example, ASCII, US-ASCII, ANSI_X3.4-1986, and ISO646-US are different names for an encoding.The Unicode Consortium co-ordinates Unicode’s development and the goal is to eventually replace existing character encoding schemes with Unicode and its standard Unicode Transformation Format (UTF) schemes.It can be considered as the core for the implementations in addition to the translation engine which perform...

Greeklish Essay

Towards the end of the century, most computer applications now supported Greek fonts thanks to the Unicode standard, however Greeklish continued to take precedence due to its speed of use, some neglect in spelling and the development of Internet jargon associated with it.Before the introduction of Unicode compatible software (notably web servers and clients), many personal and informal Greek websites were written in Greeklish.Almost all e-mail messages were also written in Greeklish, and only recently, with the full Unicode compatibility of modern e-mail clients and the gradual replacement of older software, has the use of characters Greeks became widespread.Greeklish has long been used on the Internet between Greek speakers (on forums, ...

Form feed Essay

The form feed character is sometimes used in source code text files as a page delimiter or a code section marker.The unicode standard provides the character U + 21A1 to visually represent a page break.The form feed character is represented in the ASCII code by the decimal code 12 (0xC in hexadecimal, 014 in octal) and can be represented by the combination control + L or ^ L. For example, control + L can be used to blank the screen of a Unix console like bash.This convention is widely used in LISP language and is sometimes found in C or Python.For example in the .NET framework the PrintPageEventArgs.HasMorePages property is used to indicate that a page break must be inserted.

Gutenberg Project Essay

The Gutenberg project is thus protected from the disappearance of a format, because it is unlikely that ASCII will disappear or be radically modified; the text base will therefore remain visible for a very long time.One of the strengths of the Gutenberg project, which explains its exceptional longevity, is the use of 7-bit ASCII.The principle is simple; rather than using italics, bold characters, or other special formatting often used in books, ASCII converts this type of text to uppercase letters, making text universality more accessible to all types of software.Also, the works in ASCII offer the opportunity to be downloaded as is, then converted into another format, better adapted according to the country, or the individual, to the spe...
