===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 ({{unichar|267E|PERMANENT PAPER SIGN}} and four other miscellaneous symbols<ref name="n2586r">{{cite web|url=http://unicode.org/wg2/docs/n2586r.pdf|title=Proposal to encode five miscellaneous symbols in the UCS|date=September 4, 2003|website=unicode.org}}</ref> admitted into Unicode 4.1), N3727 (the 26 [[Regional Indicator Symbol]]s used in pairs to generate [[national flag]]s in [[emoji]] contexts;<ref name="n3727">{{cite web|url=https://www.unicode.org/L2/L2009/09379-n3727-regionalindicators.pdf|title=Proposal to encode Regional Indicator Symbols in the UCS|date=September 18, 2009|website=unicode.org}}</ref> adopted into Unicode 6.0), and N4783R2 ([[chess notation]] symbols<ref name="n4783r2">{{cite web|url=https://www.unicode.org/L2/L2017/17033r2-n4783r2-chess-notation.pdf|title=Proposal to encode symbols for chess notation|date=January 26, 2017|website=unicode.org}}</ref> 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;<ref name="n1866">{{cite web|url=http://unicode.org/wg2/docs/n1866.pdf|title=Encoding Blissymbolics in Plane 1 of the UCS|date=September 10, 1998|website=unicode.org}}</ref> still listed in the SMP roadmap as of Unicode 15.0<ref name="RoadmapSMP-11-0-2">{{cite web|url=https://www.unicode.org/roadmaps/smp/smp-15-0-2.html|title=Roadmap to the SMP|date=April 9, 2023|website=unicode.org}}</ref> 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 set]]s used by [[home computer]]s (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,<ref name="L2-19-025">{{cite web|url=https://www.unicode.org/L2/L2019/19025-terminals-prop.pdf|title=Proposal to add characters from legacy computers and teletext to the UCS|date=January 4, 2019|website=unicode.org}}</ref> while 731 additional characters from L2/21-235 have been accepted for a future version of the standard.<ref>{{cite web|url=https://www.unicode.org/L2/L2022/22016.htm#170-C15|title=Approved Minutes of UTC Meeting 170|date=January 25, 2022|website=unicode.org}}</ref>
