A computer system works upon bits. In the same way, a computer reads files into binary representation which is why we need to convert text characters into binary data. Most popular character encoding types types are: ASCII and Unicode. Unicode has two further types: utf8 and utf16.SyntaxdetectCharacterEncoding(filePath)Setting Up the Environment ... Read More
