A bidirectional text contains two text directionalities, right-to-left (RTL) and left-to-right (LTR). It generally involves text containing different types of alphabets, but may also refer to boustrophedon, which is changing text direction in each row.
The Coptic script is the script used for writing the Coptic language, the most recent development of Egyptian. The repertoire of glyphs is based on the uncial Greek alphabet, augmented by letters borrowed from the 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.
The Phaistos Disc or Phaistos Disk is a disk of fired clay from the island of Crete, Greece, possibly from the middle or late Minoan Bronze Age, bearing a text in an unknown script and language. Its purpose and its original place of manufacture remain disputed. It is now on display at the archaeological museum of Heraklion. The name is sometimes spelled Phaestos or Festos.
Michael Everson is an American and Irish linguist, script encoder, typesetter, type designer and publisher. He runs a publishing company called Evertype, through which he has published over one hundred books since 2006.
The ConScript Unicode Registry is a volunteer project to coordinate the assignment of code points in the Unicode Private Use Areas (PUA) for the encoding of artificial scripts, such as those for constructed languages. It was founded by John Cowan and was maintained by him and Michael Everson. It is not affiliated with the Unicode Consortium.
ArmSCII or ARMSCII is a set of obsolete single-byte character encodings for the Armenian alphabet defined by Armenian national standard 166–9. ArmSCII is an acronym for Armenian Standard Code for Information Interchange, similar to ASCII for the American standard. It has been superseded by the Unicode standard.
ISO 15924, Codes for the representation of names of scripts, is an international standard defining codes for writing systems or scripts. Each script is given both a four-letter code and a numeric code.
In Unicode, the Sumero-Akkadian Cuneiform script is covered in three blocks in the Supplementary Multilingual Plane (SMP):
The Klingon scripts are fictional alphabetic scripts used in the Star Trek movies and television shows to write the Klingon language.
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set. The Universal Coded Character Set, most commonly called the Universal Character Set, is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other domains, to unique machine-readable data values. By creating this mapping, the UCS enables computer software vendors to interoperate, and transmit—interchange—UCS-encoded text strings from one to another. Because it is a universal map, it can be used to represent multiple languages at the same time. This avoids the confusion of using multiple legacy character encodings, which can result in the same sequence of codes having multiple interpretations depending on the character encoding in use, resulting in mojibake if the wrong one is chosen.
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.
KPS 9566 is a North Korean standard specifying a character encoding for the Chosŏn'gŭl (Hangul) writing system used for the Korean language. The edition of 1997 specified an ISO 2022-compliant 94×94 two-byte coded character set. Subsequent editions have added additional encoded characters outside of the 94×94 plane, in a manner comparable to UHC or GBK.
Runic is a Unicode block containing runic characters. It was introduced in Unicode 3.0 (1999), with eight additional characters introduced in Unicode 7.0 (2014). The original encoding of runes in UCS was based on the recommendations of the "ISO Runes Project" submitted in 1997.
In Unicode, the Sumero-Akkadian Cuneiform script is covered in three blocks in the Supplementary Multilingual Plane (SMP):
Optical Character Recognition is a Unicode block containing signal characters for OCR and MICR standards.
Early Dynastic Cuneiform is the name of a Unicode block of the Supplementary Multilingual Plane (SMP), at U+12480–U+1254F, introduced in version 8.0. It is a supplement to the earlier encoding of the cuneiform script in the two blocks U+12000–U+123FF "Cuneiform" and U+12400–U+1247F "Cuneiform Numbers and Punctuation".
ISO-IR-197 is an 8-bit, single-byte character encoding which was designed for the Sámi languages. It is a modification of ISO 8859-1, replacing certain punctuation and symbol characters with additional letters used in certain Sámi orthographies. FreeDOS calls it code page 59187.
The Tai Viet script is a Brahmic script used by the Tai Dam people and various other Thai people in Vietnam and Thailand.
