The Ugaritic writing system is a cuneiform abjad with syllabic elements used from around either 1400 BCE or 1300 BCE for Ugaritic, an extinct Northwest Semitic language. It was discovered in Ugarit, modern Ras Al Shamra, Syria, in 1928. It has 30 letters. Other languages, particularly Hurrian, were occasionally written in the Ugaritic script in the area around Ugarit, although not elsewhere.
Bitstream Cyberbit is a commercial serif Unicode font designed by Bitstream Inc. It is freeware for non-commercial uses. It was one of the first widely available fonts to support a large portion of the Unicode repertoire.
The internationalized domain name (IDN) homoglyph attack is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look alike. For example, the Cyrillic, Greek and Latin alphabets each have a letter ⟨o⟩ that has the same shape but different meaning from its counterparts.
In Unicode, a Private Use Area (PUA) is a range of code points that, by definition, will not be assigned characters by the standard. Three private use areas are defined: one in the Basic Multilingual Plane, and one each in, and nearly covering, planes 15 and 16. They are intentionally left undefined so that third parties may assign their own characters without conflicting with Unicode Consortium assignments. Under the Unicode Stability Policy, the Private Use Areas will remain allocated for that purpose in all future Unicode versions.
Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike."
Over a thousand characters from the Latin script are encoded in the Unicode Standard, grouped in several basic and extended Latin blocks. The extended ranges contain mainly precomposed letters plus diacritics that are equivalently encoded with combining diacritics, as well as some ligatures and distinct letters, used for example in the orthographies of various African languages and the Vietnamese alphabet. Latin Extended-C contains additions for Uighur and the Claudian letters. Latin Extended-D comprises characters that are mostly of interest to medievalists. Latin Extended-E mostly comprises characters used for German dialectology (Teuthonista). Latin Extended-F and -G contain characters for phonetic transcription.
GNU FreeFont is a family of free OpenType, TrueType and WOFF vector fonts, implementing as much of the Universal Character Set (UCS) as possible, aside from the very large CJK Asian character set. The project was initiated in 2002 by Primož Peterlin and is now maintained by Steve White.
In Unicode and the UCS, a compatibility character is a character that is encoded solely to maintain round-trip convertibility with other, often older, standards. As the Unicode Glossary says:
A character that would not have been encoded except for compatibility and round-trip convertibility with other standards
Many scripts in Unicode, such as Arabic, have special orthographic rules that require certain combinations of letterforms to be combined into special ligature forms. In English, the common ampersand (&) developed from a ligature in which the handwritten Latin letters e and t were combined. The rules governing ligature formation in Arabic can be quite complex, requiring special script-shaping technologies such as the Arabic Calligraphic Engine by Thomas Milo's DecoType.
In the Unicode standard, a plane is a contiguous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version 16.0, five of the planes have assigned code points (characters), and seven are named.
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 Latin-1 Supplement is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). C1 Controls (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.
IPA Extensions is a block (U+0250–U+02AF) of the Unicode standard that contains full size letters used in the International Phonetic Alphabet (IPA). Both modern and historical characters are included, as well as former and proposed IPA signs and non-IPA phonetic letters. Additional characters employed for phonetics, like the palatalization sign, are encoded in the blocks Phonetic Extensions (1D00–1D7F) and Phonetic Extensions Supplement (1D80–1DBF). Diacritics are found in the Spacing Modifier Letters (02B0–02FF) and Combining Diacritical Marks (0300–036F) blocks. Its block name in Unicode 1.0 was Standard Phonetic.
The ISO basic Latin alphabet is an international standard for a Latin-script alphabet that consists of two sets of 26 letters, codified in various national and international standards and used widely in international communication. They are the same letters that comprise the current English alphabet. Since medieval times, they are also the same letters of the modern Latin alphabet. The order is also important for sorting words into alphabetical order.
Enclosed Alphanumeric Supplement is a Unicode block consisting of Latin alphabet characters and Arabic numerals enclosed in circles, ovals or boxes, used for a variety of purposes. It is encoded in the range U+1F100–U+1F1FF in the Supplementary Multilingual Plane.
Arabic Presentation Forms-A is a Unicode block encoding contextual forms and ligatures of letter variants needed for Persian, Urdu, Sindhi and Central Asian languages. This block also allocates 32 noncharacters in Unicode, designed specifically for internal use.
Arabic Presentation Forms-B is a Unicode block encoding spacing forms of Arabic diacritics, and contextual letter forms. The special codepoint ZWNBSP is also here, which is only meant for a byte order mark. The block name in Unicode 1.0 was Basic Glyphs for Arabic Language; its characters were re-ordered in the process of merging with ISO 10646 in Unicode 1.0.1 and 1.1.
Armenian is a Unicode block containing characters for writing the Armenian language, both the classical and reformed orthographies. Five Armenian ligatures are encoded in the Alphabetic Presentation Forms block.
Hebrew is a Unicode block containing characters for writing the Hebrew, Yiddish, Ladino, and other Jewish diaspora languages.
Syriac is a Unicode block containing characters for all forms of the Syriac alphabet, including the Estrangela, Serto, Eastern Syriac, and the Christian Palestinian Aramaic variants. It is used in Literary Syriac, Neo-Aramaic, and Arabic among Syriac-speaking Christians. It was used historically to write Armenian, Persian, Ottoman Turkish, and Malayalam.
