UTF-16LE store bytes in little endian order, while UTF-16BE stores bytes in big endian order in disk. Hello there? What is difference between UTF-16, UTF-16LE and UTF-16BE? Are they same?įebruat 5:13 They are not same.

in Eclipse it could be different than your Linux host. Javin Yes, Java String uses UTF-16 but when you convert Byte array to characters, Java uses platform's default character encoding. Hello One point to note is that, UTF-8 can go until 6 bytes, i hope i am not wrong here.

Valid code points for Unicode are U+0000 to U+10FFFF.' This coded character set define range of valid code points. Is there a different encoding you were reffering to?įebruat 5:42 points are the numbers that are used in coded character set where coded character set represent collection of characters and each character will assign a unique number. You mention the default encoding in Java is UTF-8 but at least Character and String have the default UTF-16 (). You said: 'Java programming language has extensive support for different charset and character encoding, by default it use UTF-8.' Then you said: 'Also, worth knowing is that Java Strings are represented using UTF-16 bit characters' 'BTW, if character's code point is greater than 127, ' what is Character's CODE POINT ? plz explain. You can see how different scheme takes different number of bytes to represent same character. Here is an example, which shows how different characters are mapped to bytes under different character encoding scheme e.g. Given dominance of ASCII in past this was the main reason of initial acceptance of Unicode and UTF-8. UTF-8 file containing only ASCII characters has the same encoding as an ASCII file, which means English text looks exactly the same in UTF-8 as it did in ASCII. UTF-8 has an advantage where ASCII are most used characters, in that case most characters only need one byte. UTF-8 is compatible with ASCII while UTF-16 is incompatible with ASCII On the other hand UTF-32 is fixed 4 bytes.Ģ. UTF-16 is also variable length character encoding but either takes 2 or 4 bytes. In short, UTF-8 is variable length encoding and takes 1 to 4 bytes, depending upon code point. Only code points 128 and above are stored using 2,3 or in fact, up to 4 bytes. In UTF-8, every code point from 0-127 is stored in a single bytes. UTF-8 uses one byte at the minimum in encoding the characters while UTF-16 uses minimum two bytes. BTW, despite, both UTF-8 and UTF-16 uses Unicode characters and variable width encoding, there are some difference between them as well.ġ. The fundamental difference between UTF-32 and UTF-8, UTF-16 is that former is fixed width encoding scheme, while later duo is variable length encoding.

Java programming language has extensive support for different charset and character encoding, by default it uses UTF-8. In short, you just need a character encoding scheme to interpret a stream of bytes, in the absence of character encoding, you cannot show them correctly. UTF stands for Unicode Transformation, which defines an algorithm to map every Unicode code point to a unique byte sequence.įor example, for character A, which is Latin Capital A, Unicode code point is U+0041, UTF-8 encoded bytes are 41, UTF-16 encoding is 0041, and Java char literal is 'A'. 16-bit for UTF-16, 32 bits for UTF-32 and 8-bit for UTF-8). On the other hand UTF-16, UTF-32 and UTF-8 are encoding schemes, which describe how these values (code points) are mapped to bytes (using different bit values as a basis e.g. A character set is nothing but list of characters, where each symbol or character is mapped to a numeric value, also known as code points. Since there are so many characters and symbols in the world, a character set is required to support all those characters. There are two things, which are important to convert bytes to characters, a character set and an encoding. Now, let's start with what is character encoding and why it's important? Well, character encoding is an important concept in the process of converting byte streams into characters, which can be displayed. On the other hand, UTF-32 is a fixed-width encoding scheme and always uses 4 bytes to encode a Unicode code point.

BTW, if the character's code point is greater than 127, the maximum value of byte then UTF-8 may take 2, 3 o 4 bytes but UTF-16 will only take either two or four bytes. UTF-8 uses a minimum of one byte, while UTF-16 uses a minimum of 2 bytes. The main difference between UTF-8, UTF-16, and UTF-32 character encoding is how many bytes it requires to represent a character in memory.
