These two processes involve changing the format of content for optimal transmission or storage. Why do we use encoding and decoding?Įncoding and decoding are used in many forms of communications, including computing, data communications, programming, digital electronics and human communications. It is a process of interpretation and translation of coded information into a comprehensible form. The decoding of a message is how an audience member is able to understand, and interpret the message.
It is very important how a message will be encoded it partially depends on the purpose of the message. To convert a string of bytes to a unicode string is known as decoding. To represent a unicode string as a string of bytes is known as encoding. PythonServer Side ProgrammingProgramming.
It also does the reverse, reading in binary digits and converting them back to characters. This means that UTF-8 takes the code point for a given Unicode character and translates it into a string of binary. UTF-8 is a Unicode character encoding method. But, in principle, UTF-8 is only one of the possible ways of encoding Unicode characters. UTF-8 is the most widely used way to represent Unicode text in web pages, and you should always use UTF-8 when creating your web pages and databases. where charsetName is the specific charset by which the String is encoded into an array of bytes. The getBytes() method encodes a String into a sequence of bytes and returns a byte array. In order to convert a String into UTF-8, we use the getBytes() method in Java. It can translate any Unicode character to a matching unique binary string, and can also translate the binary string back to a Unicode character. Rather than using 7 or 8 bits, Unicode represents each character in 16 bits enabling it to handle up to 65,536 ( = 216) distinct sym- bols. What is used for encoding alphabet? Unicode is a text encoding standard designed to embrace all the world's alphabets.
This is a good way to protect your data from theft since any stolen files would not be usable. Encoding keeps your data safe since the files are not readable unless you have access to the algorithms that were used to encode it.
