Get encoding information of a character in UTF-8, UTF-16 and UTF-32 encodings.
npm install -S utf-infoconst utfInfo = require( 'utf-info' );
// syntax:
utfInfo( character, encoding );
// character => single Unicode character (string)
// encoding => valid UTF encoding (string) viz. utf-8, utf-16, and utf-32
// examples:
const result = utfInfo( '😊' ); // character `😊`
// const result = utfInfo( '\x41', 'utf-8' ); // '\x41' is ASCII escape character `A`
// const result = utfInfo( '\u0906', 'utf-16' ); // '\u0906' is Unicode escape for character `आ`
