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

Usage

Install

npm i convert-unicode-fonts
yarn add convert-unicode-fonts

API

import { transform, getFonts, revertTransform } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('Hello', fonts['scriptItalic'])
const normal = revertTransform(s)

Join

The option join will join the characters with given character. Take the following examples with different space characters:

no join

import { transform, getFonts } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('abcdefXZYUPO91234 hello WORLD', fonts['circled'])
// ⒶⒷⒸⒹⒺⒻⓍZⓎⓊⓅⓄ⑨①②③④ ⒽⒺⓁⓁⓄ ⓌⓄⓇⓁⒹ

thin space

import { transform, getFonts } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('abcdefXZYUPO91234 hello WORLD', fonts['circled'], "0x2009")
// Ⓐ Ⓑ Ⓒ Ⓓ Ⓔ Ⓕ Ⓧ Z Ⓨ Ⓤ Ⓟ Ⓞ ⑨ ① ② ③ ④   Ⓗ Ⓔ Ⓛ Ⓛ Ⓞ   Ⓦ Ⓞ Ⓡ Ⓛ Ⓓ 

ideographic space

import { transform, getFonts } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('abcdefXZYUPO91234 hello WORLD', fonts['circled'], "0x3000") # hair space
Ⓐ　Ⓑ　Ⓒ　Ⓓ　Ⓔ　Ⓕ　Ⓧ　Z　Ⓨ　Ⓤ　Ⓟ　Ⓞ　⑨　①　②　③　④　 　Ⓗ　Ⓔ　Ⓛ　Ⓛ　Ⓞ　 　Ⓦ　Ⓞ　Ⓡ　Ⓛ　Ⓓ

zero width space

import { transform, getFonts } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('abcdefXZYUPO91234 hello WORLD', fonts['circled'], "0x200b") 
// Ⓐ​Ⓑ​Ⓒ​Ⓓ​Ⓔ​Ⓕ​Ⓧ​Z​Ⓨ​Ⓤ​Ⓟ​Ⓞ​⑨​①​②​③​④​ ​Ⓗ​Ⓔ​Ⓛ​Ⓛ​Ⓞ​ ​Ⓦ​Ⓞ​Ⓡ​Ⓛ​Ⓓ

backspace

import { transform, getFonts } from 'convert-unicode-fonts';
const fonts = getFonts()
const s = transform('abcdefXZYUPO91234 hello WORLD', fonts['circled'], "0x0008") 
// Ⓓ

WARNING

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.
