How it works

These 121 rare symbols are rare by a test, not by taste: each is marked obsolete, excluded, limited-use or uncommon in Unicode's security data, or sits in a block kept for one subject. With no font for one, a device shows a box.

Read the full guide

What makes a symbol rare here

The test is Identifier_Type, a property in Unicode's security data (UTS #39). It files 15 of these characters as obsolete, one as uncommon, 32 under limited-use scripts and 52 under excluded scripts. The other 21 come from five blocks that each serve one subject: Alchemical Symbols, Ancient Symbols, Counting Rod Numerals, Tai Xuan Jing Symbols and Ancient Greek Numbers.

Before you paste one anywhere

All 121 drew with the system fonts of the computer they were checked on, which says nothing about yours, so paste one into a draft first. Of the 121, 76 sit above U+FFFF, where software counting UTF-16 units sees two per character. The newest, a Hmong circled sign, dates from Unicode 12.0 (2019).

Tips

The search box takes a status: obsolete finds 15 tiles, limited 32 and excluded 52.
Type a year to see what that version added: 2008 brings up 16, the many-eyed O among them.
Or search by look: eye finds the four eyed O letters, wheel 5 tiles, egypt the 12 hieroglyphs.

Questions and answers

What is the ꙮ symbol?

The Cyrillic letter multiocular O, U+A66E. Wikipedia traces it to one 15th-century psalter, in the phrase many-eyed seraphim. Unicode added it in version 5.1 (2008) with seven eyes, and the chart glyph was redrawn with ten for version 15.0.

Why does a rare symbol show as a box?

A character is only a number until a font draws it. When no font on the device covers that number, the device shows a box instead. Nothing was lost in the paste: the same text reads correctly wherever a font exists.

What is the rarest symbol in Unicode?

The Unicode data files carry no usage counts, so they name no rarest character. They record status instead: obsolete means no longer in modern use, and excluded means a script, such as cuneiform, that Unicode advises against in identifiers such as domain names.

How this list was compiled: Built by script on 2026-09-19, not typed by hand. Every character was checked against UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt): the code points and the character names in the notes come from that file, names in sentence case. Block names come from Blocks.txt (https://www.unicode.org/Public/18.0.0/ucd/Blocks.txt) and the Unicode version each character arrived in from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), both version 18.0.0. The year beside each version is from the Unicode Consortium's release dates (https://www.unicode.org/history/publicationdates.html). Other names and uses of a character come from the annotations in NamesList.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt). The subheads Forfeda, Section marks, Ancient Roman epigraphic letters and Roman coin symbols are from the same file. What counts as rare is not this site's taste. The status in each note is the character's Identifier_Type in IdentifierType.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/security/IdentifierType.txt), defined in Unicode Technical Standard #39 (https://www.unicode.org/reports/tr39/): Obsolete, Exclusion (a script in Table 4 of https://www.unicode.org/reports/tr31/), Limited_Use (a script in Table 7) or Uncommon_Use. A character with none of the four is here only if its whole block serves one subject: Alchemical Symbols, Ancient Symbols, Counting Rod Numerals, Tai Xuan Jing Symbols or Ancient Greek Numbers. The build refuses anything else, and anything from the everyday symbol blocks. What each hieroglyph depicts is its kEH_Desc in Unikemet.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/Unikemet.txt). From Wikipedia: the multiocular O, its psalter and its seven and ten eyes, and the one-eyed and two-eyed letters (https://en.wikipedia.org/wiki/Multiocular_O); sampi as 900 and koppa as 90 (https://en.wikipedia.org/wiki/Greek_numerals); sho and Bactrian (https://en.wikipedia.org/wiki/Sho_(letter)); the cuneiform sign an (https://en.wikipedia.org/wiki/Dingir); the dates of the Bamum phases (https://en.wikipedia.org/wiki/Bamum_script); yaz on the Berber flag (https://en.wikipedia.org/wiki/Berber_flag); the 81 tetragrams and Yang Xiong (https://en.wikipedia.org/wiki/Taixuanjing). Every character was drawn on 2026-09-19 with the system fonts of macOS 26.6.2 and none came out as a box; a character that did was dropped. That says nothing about any other device. Which rare characters made the page, the tile names and the search words are this site's own choice. All sources were checked on 2026-09-19. Licence: own work
