The Emoji рџ has unicode code point U+1F62D. The red bits indicate 3 byte encoding, the black ones are filler bits and the blues represent the code point. The filling is done starting with the least significant bit of the code point mapped to the least significant of the third byte. Filling these bits in the above encoding format gives us the UTF-8 3 byte encoding representation of б№Ќ show below. The binary value for the hex code point 0x1E4D is 1111001001101. The latin character б№Ќ with code point U+1E4D is be represented using 3 byte encoding as it is larger than the maximum value that can be represented using 2 byte encoding.ДЄ 3 byte encoding is identified by the presence of the bit sequence 1110 in the first byte and 10 in the second and third bytes. The black coloured zeros are used to fill up the empty bits in the byte. The binary digits in blue 11110001 represent the code point U+00F1's binary value and the ones in red are the 2 byte encoding identifiers. The filling is done starting with the least significant bit of the code point being mapped to the least significant bit of the second byte. Filling these bits in the 2 byte encoding format, we get the UTF-8 2 byte encoding representation of Г± shown below. The binary value of the unicode code point U+00F1 is 1111 0001. This value is larger than the maximum value that can be represented using 1 byte encoding format and hence this alphabet will be represented using UTF-8 2 byte encoding.Дў byte encoding is identified by the presence of the bit sequence 110 in the first bit and 10 in the second bit. The latin alphabet Г± with code point U+00F1 has binary value 11110001. The red 0 bit indicates that 1 byte encoding is used and the remaining bits represent the code point UTF-8 2 byte encoding The English alphabet A has unicode code point U+0041. UTF-8 1 byte encodingДЄ 1 byte encoding is identified by the presence of 0 in the first bit. Variable sized encoding means the code points are represented using 1, 2, 3 or 4 bytes depending on their size. UTF-8 encoding is a variable sized encoding scheme to represent unicode code points in memory. This is where character encodings come into the picture. Now that we know what is unicode and how each alphabet in the world is assigned to a unique code point, we need a way to represent these code points in the computer's memory. Please visit to know the code points for all languages and alphabets of the world UTF-8 Encoding The English alphabet A is represented as U+0041 U+ denotes unicode and 1E4D is the hexadecimal value assigned to the character б№Ќ The latin character б№Ќ is referred using the code point U+1E4D These unique numbers are called as code points in the unicode terminology. This ensured that there are no collisions between alphabets of different languages. Unicode character set mapped each character in the world to a unique number. This is where Unicode character set came to save the day. So if an email written by an Indian contains the alphabet а¤ and if it is read by a person in Vietnam it would appear as б»ќ. For instance the decimal value 182 was used by the Vietnamese to represent the Vietnamese alphabet б»ќ whereas the same value 182 was used by the Indians to represent the Hindi alphabet а¤. People came up with different ways of using the remaining eight bit which represented decimal values from 128 to 255 and collisions started to happen. This is where things started getting messy. It can be inferred from the above binary representation that decimal values 0 to 127 can be represented using 7 bits leaving the 8th bit free. Lets look at the binary representation of 0 and 127 in 8 bit bytes. The table below provides the ASCII characters and their corresponding Decimal and Hex values.ДЄs you can infer from the above table, the ASCII values can be represented from 0 to 127 in the decimal number system. The English language has only 26 alphabets and a few other special characters and symbols. In the older days of computing, ASCII code was used to represent characters.
