Text & Unicode Glossary
Plain-English definitions for Unicode, internet text styles, encoding systems, and everything in between.
Unicode
Unicode is the universal character encoding standard that assigns a unique number to every character in every language, script, and symbol system used worldwide.
Read definition →Zalgo Text
Zalgo text is glitchy, corrupted-looking text created by stacking large numbers of Unicode combining characters above and below ordinary letters.
Read definition →Morse Code
Morse code is a character-encoding system that represents letters, numbers, and punctuation using sequences of short signals (dots) and long signals (dashes).
Read definition →Kaomoji
Kaomoji are Japanese text emoticons made entirely from Unicode characters, designed to be read upright rather than sideways like Western emoticons.
Read definition →Leet Speak
Leet speak (also written as 1337) is an internet alphabet that substitutes letters with visually similar numbers and symbols, originally developed in early hacker and gaming culture.
Read definition →Fancy Font
A fancy font, in the context of online text tools, refers to Unicode character sets that visually mimic different typeface styles — bold, italic, cursive, script, fraktur — and can be pasted anywhere.
Read definition →Aesthetic Text
Aesthetic text is a visual text style that uses Unicode fullwidth characters and deliberate spacing to create the spaced-out, wide-letter look associated with vaporwave and internet aesthetics.
Read definition →Invisible Character
An invisible character is a real Unicode character that takes up space and is treated as a character by software, but renders as completely blank with no visible shape.
Read definition →Bubble Text
Bubble text uses Unicode enclosed alphanumeric characters — letters inside circles — to create a distinctive "circled" or "bubbled" visual text style.
Read definition →ASCII Art
ASCII art is visual artwork created using the 95 printable characters of the ASCII character set, arranged spatially to form images, patterns, and text designs.
Read definition →Pig Latin
Pig Latin is a language game in English where words are altered by moving leading consonants to the end and adding -ay, turning "hello" into "ellohay".
Read definition →Braille Alphabet
Braille is a tactile writing system using raised dot patterns arranged in cells to represent letters, numbers, and punctuation for people who are blind or have low vision.
Read definition →NATO Phonetic Alphabet
The NATO phonetic alphabet is a standardised set of code words — Alpha, Bravo, Charlie, Delta — assigned to each letter to ensure clear spoken communication over radio and telephone.
Read definition →Strikethrough Text
Strikethrough text has a horizontal line drawn through the middle of each letter, created in plain text using Unicode combining strikethrough characters that work anywhere text is accepted.
Read definition →Old English Font
Old English font refers to Blackletter or Fraktur script — the angular, gothic-style lettering used in medieval manuscripts and German printing, now used decoratively in tattoos, logos, and social media.
Read definition →Cursive Text
Cursive text in the Unicode context refers to script-style letters from the Mathematical Script block — flowing, handwritten-style Unicode characters that paste into Instagram, Discord, and other platforms.
Read definition →Superscript Text
Superscript text consists of small characters positioned above the normal text baseline, used in mathematics, footnotes, and social media styling using Unicode superscript characters.
Read definition →Text Case
Text case refers to the capitalisation pattern of letters in text — uppercase, lowercase, title case, sentence case, camelCase, snake_case, and other conventions used in writing and programming.
Read definition →Binary Code
Binary code represents information using only two digits — 0 and 1 — and is the fundamental language that all digital computers use to store, process, and transmit data.
Read definition →Alien Alphabet
Alien alphabet refers to fictional or stylised symbol systems used to represent human language in a visually extraterrestrial way — popular in science fiction, games, and social media text generators.
Read definition →Fullwidth Text
Fullwidth text uses Unicode fullwidth characters — wide versions of standard letters and symbols that take up double the horizontal space — creating the spaced-out aesthetic text style popular in vaporwave and lo-fi content.
Read definition →Tiny Text
Tiny text uses Unicode superscript and small capital characters to create text that appears significantly smaller than normal inline text — popular for social media bios, captions, and decorative content.
Read definition →Mirror Text
Mirror text reverses the order of characters and substitutes each letter with its Unicode mirror equivalent, producing text that reads correctly when reflected in a mirror or flipped horizontally.
Read definition →Vaporwave Text
Vaporwave text is the typographic style associated with the vaporwave music and visual aesthetic — using fullwidth Unicode characters, spaced-out letters, and Japanese katakana to create a dreamy, retro-futuristic look.
Read definition →Upside Down Text
Upside down text flips each letter to a Unicode character that resembles the original letter rotated 180 degrees, and reverses the word order so the result reads correctly when physically turned upside down.
Read definition →Rainbow Text
Rainbow text cycles through multiple colours — red, orange, yellow, green, blue, and violet — applied to individual characters or words, creating a colourful gradient effect across the full text.
Read definition →Backwards Text
Backwards text reverses the character order of input — the last letter becomes the first — used for wordplay, social media aesthetics, simple encoding, and palindrome discovery.
Read definition →Gradient Text
Gradient text transitions smoothly between two or more colours across the length of the text — from one colour at the start to another at the end — created using CSS, HTML, or visual design tools.
Read definition →Lorem Ipsum
Lorem ipsum is standard placeholder text used in design, publishing, and web development to fill layouts during the design process — it looks like natural text but is deliberately meaningless scrambled Latin.
Read definition →Unicode Character
A Unicode character is any single text unit defined in the Unicode standard — every letter, digit, emoji, symbol, or script character that has been assigned a unique code point in the universal encoding system.
