Comparison Of Unicode Encodings
This article compares Unicode encodings in two types of environments: 8-bit clean environments, and environments that forbid the use of byte values with the high bit set. Originally, such prohibitions allowed for links that used only seven data bits, but they remain in some standards, so some standard-conforming software must generate messages that comply with the restrictions. The Standard Compression Scheme for Unicode and the Binary Ordered Compression for Unicode are excluded from the comparison tables because it is difficult to simply quantify their size. Compatibility issues A UTF-8 file that contains only ASCII characters is identical to an ASCII file. Legacy programs can generally handle UTF-8-encoded files, even if they contain non-ASCII characters. For instance, the C printf function can print a UTF-8 string because it only looks for the ASCII '%' character to define a formatting string. All other bytes are printed unchanged. UTF-16 and UTF-32 are incompatible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Thaana
Thaana, Tãna, Taana or Tāna ( ) is the present writing system of the Maldivian language spoken in the Maldives. Thaana has characteristics of both an abugida (diacritics, vowel-killer strokes) and a true alphabet (all vowels are written), with consonants derived from indigenous and Arabic numerals, and vowels derived from the vowel diacritics of the Arabic abjad. Maldivian orthography in Thaana is largely phonemic. Name H. C. P. Bell, the first serious researcher of Maldivian documents, used the spelling ''Tāna,'' as the initial consonant is unaspirated. The spelling ''Thaana'' was adopted in the mid-1970s, when the government of the Maldives embarked on a short period of Romanization; /t/ was transcribed , as was used for the voiceless retroflex plosive . History The Thaana script first appeared in a Maldivian inscription towards the beginning of the 17th century in a crude initial form known as Gabulhi ('incomplete') Thaana which was written '' scripta co ...

Syriac Alphabet
The Syriac alphabet ( ) is a writing system primarily used to write the Syriac language since the 1st century. It is one of the Semitic languages, Semitic abjads descending from the Aramaic alphabet through the Palmyrene alphabet, and shares similarities with the Phoenician alphabet, Phoenician, Hebrew alphabet, Hebrew, Arabic alphabet, Arabic and Sogdian alphabet, Sogdian, the precursor and a direct ancestor of the traditional Mongolian scripts. Syriac is written from right to left in horizontal lines. It is a cursive script where most—but not all—letters connect within a word. There is no letter case distinction between upper and lower case letters, though some letters change their form depending on their position within a word. Spaces word divider, separate individual words. All 22 letters are consonants (called , ). There are optional diacritic marks (called , ) to indicate the vowel (, ) and #Letter alterations, other features. In addition to the sounds of the language, ...

Arabic Alphabet
The Arabic alphabet, or the Arabic abjad, is the Arabic script as specifically codified for writing the Arabic language. It is a unicase, unicameral script written from right-to-left in a cursive style, and includes 28 letters, of which most have contextual letterforms. Unlike the modern Latin alphabet, the script has no concept of letter case. The Arabic alphabet is an abjad, with only consonants required to be written (though the long vowels – ''ā ī ū'' – are also written, with letters used for consonants); due to its optional use of diacritics to notate vowels, it is considered an impure abjad. Letters The basic Arabic alphabet contains 28 letter (alphabet), letters. Forms using the Arabic script to write other languages added and removed letters: for example ⟨پ⟩ is often used to represent in adaptations of the Arabic script. Unlike Archaic Greek alphabets, Greek-derived alphabets, Arabic has no distinct letter case, upper and lower case letterforms. Many le ...

Hebrew Alphabet
The Hebrew alphabet (, ), known variously by scholars as the Ktav Ashuri, Jewish script, square script and block script, is a unicase, unicameral abjad script used in the writing of the Hebrew language and other Jewish languages, most notably Yiddish, Judaeo-Spanish, Ladino, Judeo-Arabic languages, Judeo-Arabic, and Judeo-Persian. In modern Hebrew, vowels are increasingly introduced. It is also used informally in Israel to write Levantine Arabic, especially among Druze in Israel, Druze. It is an offshoot of the Aramaic alphabet, Imperial Aramaic alphabet, which flourished during the Achaemenid Empire and which itself derives from the Phoenician alphabet. Historically, a different abjad script was used to write Hebrew: the original, old Hebrew script, now known as the Paleo-Hebrew alphabet, has been largely preserved in a variant form as the Samaritan script, Samaritan alphabet, and is still used by the Samaritans. The present ''Jewish script'' or ''square script'', on the cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armenian Alphabet
The Armenian alphabet (, or , ) or, more broadly, the Armenian script, is an alphabetic writing system developed for Armenian and occasionally used to write other languages. It is one of the three historical alphabets of the South Caucasus. It was developed around 405 AD by Mesrop Mashtots, an Armenian linguist and ecclesiastical leader. The script originally had 36 letters. Eventually, two more were adopted in the 13th century. In reformed Armenian orthography (1920s), the ligature is also treated as a letter, bringing the total number of letters to 39. The Armenian word for 'alphabet' is ('), named after the first two letters of the Armenian alphabet: ' and '. Armenian is written horizontally, left to right. History and development Possible antecedents One of the classical accounts of the existence of an Armenian alphabet before Mesrop Mashtots comes from Philo of Alexandria (20 BCAD 50), who in his writings notes that the work of the Greek philosoph ...

Coptic Script
The Coptic alphabet is the Writing system, script used for writing the Coptic language, the most recent development of Egyptian language, Egyptian. The repertoire of glyphs is based on the uncial Greek alphabet, augmented by letters borrowed from the Egyptian Demotic (Egyptian), Demotic. It was the first alphabetic script used for the Egyptian language. There are several Coptic alphabets, as the script varies greatly among the various dialects and eras of the Coptic language. History The Coptic script has a long history going back to the Ptolemaic Kingdom, when the Greek alphabet was used to Transcription (linguistics), transcribe Demotic (Egyptian), Demotic texts, with the aim of recording the correct pronunciation of Demotic. As early as the sixth century BC and as late as the second century AD, an entire series of ancient Egyptian religion, pre-Christian religious texts were written in what scholars term Old Coptic, Egyptian language texts written in the Greek alphabet.

Greek Alphabet
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It was derived from the earlier Phoenician alphabet, and is the earliest known alphabetic script to systematically write vowels as well as consonants. In Archaic Greece, Archaic and early Classical Greece, Classical times, the Greek alphabet existed in Archaic Greek alphabets, many local variants, but, by the end of the 4th century BC, the Ionia, Ionic-based Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard throughout the Greek-speaking world and is the version that is still used for Greek writing today. The letter case, uppercase and lowercase forms of the 24 letters are: : , , , , , , , , , , , , , , , , , , , , , , , The Greek alphabet is the ancestor of several scripts, such as the Latin script, Latin, Gothic alphabet, Gothic, Coptic script, Coptic, and Cyrillic scripts. Throughout antiquity, Greek had only a single uppercas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin-script Alphabet
A Latin-script alphabet (Latin alphabet or Roman alphabet) is an alphabet that uses Letter (alphabet), letters of the Latin script. The 21-letter archaic Latin alphabet and the 23-letter classical Latin alphabet belong to the oldest of this group. The 26-letter modern Latin alphabet is the newest of this group. Encoding The 26-letter ISO basic Latin alphabet (adopted from the earlier ASCII) contains the 26 letters of the English alphabet. To handle the many other alphabets also derived from the classical Latin one, ISO and other telecommunications groups "extended" the ISO basic Latin multiple times in the late 20th century. More recent international standards (e.g. Unicode) include those that achieved ISO adoption. Key types of differences Apart from alphabets for modern spoken languages, there exist phonetic alphabets and spelling alphabets in use derived from Latin script letters. Historical languages may also have used (or are now studied using) alphabets that are deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C0 Controls And Basic Latin
The Basic Latin Unicode block, sometimes informally called C0 Controls and Basic Latin, is the first block of the Unicode standard, and the only block which is encoded in one byte in UTF-8. The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character. The Basic Latin block was included in its present form from version 1.0.0 of the Unicode Standard, without addition or alteration of the character repertoire. Its block name in Unicode 1.0 was ASCII. Table of characters : The letter U+005C (\) may show up as a Yen(¥) or Won(₩) sign in Japanese/Korean fonts mistaking Unicode (especially UTF-8) as a legacy character set which replaced the backslash with these signs. Subheadings The C0 Controls and Basic Latin block contains six subheadings. C0 controls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
