Encoding of scripts

Everson has been actively involved in the encoding of many scripts^[9] in the Unicode and ISO/IEC 10646 standards, including Avestan, Balinese, Bamum, Bassa Vah, Batak, Braille, Brāhmī, Buginese, Buhid, Unified Canadian Aboriginal Syllabics, Carian, Cham, Cherokee, Coptic, Cuneiform, Cypriot, Deseret, Duployan, Egyptian hieroglyphs, Elbasan, Ethiopic, Georgian, Glagolitic, Gothic, Hanunóo, Imperial Aramaic, Inscriptional Pahlavi, Inscriptional Parthian, Javanese, Kayah Li, Khmer, Lepcha, Limbu, Linear A, Linear B, Lycian, Lydian, Mandaic, Manichaean, Meitei Mayek, Mongolian, Myanmar, Nabataean, New Tai Lue, N'Ko, Ogham, Ol Chiki, Old Hungarian, Old Italic, Old North Arabian, Old Persian, Old South Arabian, Old Turkic, Osmanya, Palmyrene, Phaistos Disc, Phoenician, Rejang, Runic, Samaritan, Saurashtra, Shavian, Sinhala, Sundanese, Tagalog, Tagbanwa, Tai Le, Tai Tham, Thaana, Tibetan, Ugaritic, Vai, and Yi, as well as many characters belonging to the Latin, Greek, Cyrillic, and Arabic scripts.

Encoding of symbols

Everson authored or co-authored proposals for many symbol characters for encoding into Unicode and ISO/IEC 10646. Among those proposals submitted to ISO/IEC JTC 1/SC 2/WG 2 that have been accepted and encoded: N2586R (U+267E ♾ PERMANENT PAPER SIGN and four other miscellaneous symbols^[10] admitted into Unicode 4.1), N3727 (the 26 Regional Indicator Symbols used in pairs to generate national flags in emoji contexts;^[11] adopted into Unicode 6.0), and N4783R2 (chess notation symbols^[12] encoded into Unicode 11.0).

Among proposals that have not yet been approved for encoding: N1866 (an early proposal for encoding Blissymbols into the Supplementary Multilingual Plane of Unicode;^[13] still listed in the SMP roadmap as of Unicode 15.0^[14] although no further action had been taken on it for years).

Everson, along with Doug Ewell, Rebecca Bettencourt, Ricardo Bánffy, Eduardo Marín Silva, Elias Mårtenson, Mark Shoulson, Shawn Steele, and Rebecca Turner, is a contributor to the Terminals Working Group researching obscure characters found in legacy character sets used by home computers (or "microcomputers"), terminals, and other legacy devices made from the mid-1970s until the mid-1980s; thanks to their proposal L2/19-025, 212 graphic characters for compatibility with MSX, Commodore 64, and other microcomputers of the era, as well as Teletext, were encoded in the Symbols for Legacy Computing block,^[15] while 731 additional characters from L2/21-235 have been accepted for a future version of the standard.^[16]

Font development

In 1995 he designed a Unicode font, Everson Mono, a monospaced typeface with more than 4,800 characters. This font was the third Unicode-encoded font to contain a large number of characters from many character blocks, after Lucida Sans Unicode and Unihan font (both 1993). In 2007 he was commissioned by the International Association of Coptic Studies to create a standard free Unicode 5.1 font for Coptic, Antinoou, using the Sahidic style.^[17]

Conscript Unicode Registry

Together with John Cowan, he is also responsible for the ConScript Unicode Registry, a project to coordinate the mapping of artificial scripts into the Unicode Private Use Area. Among the scripts "encoded" in the CSUR, Shavian and Deseret were eventually formally adopted into Unicode; two other conscripts under consideration are Tolkien's scripts of Tengwar and Cirth.

Language and locale information

Everson has also created locale and language information for many languages, from support for the Irish language and the other Celtic languages to the minority Languages of Finland.^[18] In 2000, together with Trond Trosterud, he co-authored Software localization into Nynorsk Norwegian, a report commissioned by the Norwegian Language Council. In 2003 he was commissioned by the United Nations Development Programme to prepare a report^[19] on the computer locale requirements for the major languages of Afghanistan (Pashto, Dari, and Uzbek), co-authored by Roozbeh Pournader, which was endorsed by the Ministry of Communications of the Afghan Transitional Islamic Administration.^[20] More recently, UNESCO's Initiative B@bel^[21] funded Everson's work to encode the N'Ko and Balinese scripts.^[22]

Work on a standard for Cornish

In 2007 he co-authored a proposal for a new standard written form of Cornish, called Kernowek Standard.^[23] Following the publication of the Standard Written Form in 2008, Everson and a group of other users examined the specification and implemented a set of modifications to it, publishing a formal specification in 2012.^[24]

Publishing at Evertype

As of March 2014^[update] Everson operates a publishing company, Evertype, through which he has published a total of 295 books.^[25] These include a wide range of titles by various authors and editors, with Everson himself as co-author of one, editor of several, and having adapted or revised several more. He also designed fonts for several.^[25]

Everson has a particular interest in Gaelic typeface design, and does a considerable amount of work typesetting books in Irish for publication by Evertype.^[26]

Another project consists of his publications of translations of Alice's Adventures in Wonderland in many languages, amongst which are minority languages and constructed languages.^[27] Translations are available in Cornish, Esperanto, French, German, Hawaiian, Irish, Italian, Jèrriais, Ladino, Latin, Lingua Franca Nova, Lingwa de planeta, Low German, Manx, Mennonite Low German, Borain Picard, Sambahsa, Scots, Shavian transliteration, Swedish, Ulster Scots and Welsh, with several other translations being prepared.^{[citation needed]}
