Explanation: unicode charset supports extra font families, so we replace normal character 'a' (char code 97) with character '𝓪' (char code 55349). So this are not currently font families or different fonts, it's the same font, that provides this special characters, some of them.

Note: these are not using any ansi escape sequences. We could use those to add colors, bold, underline, etc in the command line.

Some Unicode categories that contain these type of characters are:

  • Mathematical Alphanumeric Symbols



npm i -g unicode-fonts


unicode-fonts --list
unicode-fonts --font scriptItalic --input "My name is Sebastian Gurin"


const fonts = getFonts()
const s = transform('Hello', fonts['scriptItalic'])


In general it's a bad idea to use these characters to store text. The only useful situatoin where you would want to store text using these, is if you want to prevent text searches to find a string.

These characters should be only used to render normal text in mediums with limited fonts, like a terminal.


  • input form stdin


  • JavaScript source code transformation that format Identifiers. Variable identifiers with font1, type identifiers with font2, property / member identifiers with font3, parameter identifiers w font4... etc
