UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [1] Almost every webpage is stored in UTF-8.
UTF-8: A variable-length character encoding (1 to 4 bytes long). UTF-8 is backwards compatible with ASCII and the preferred encoding for e-mail and web pages. UTF-16: A variable-length character encoding. UTF-16 is used in all major operating systems like Windows, IOS, and Unix.
3 kwi 2024 · UTF-8 encodes a character into a binary string of one, two, three, or four bytes. UTF-16 encodes a Unicode character into a string of either two or four bytes. This distinction is evident from their names. In UTF-8, the smallest binary representation of a character is one byte, or eight bits.
UTF-8 uses one to four units of eight bits, and UTF-16 uses one or two units of 16 bits, to cover the entire Unicode of 21 bits maximum. Units use prefixes so that character boundaries can be spotted, and more units mean more prefixes that occupy bits.
UTF-8 (ang. 8-bit Unicode Transformation Format) – system kodowania Unicode, wykorzystujący od 1 do 4 bajtów do zakodowania pojedynczego znaku, w pełni kompatybilny z ASCII. Jest najczęściej wykorzystywany do przechowywania napisów w plikach i komunikacji sieciowej.
3 kwi 2022 · UTF-8 is a character encoding system. It lets you represent characters as ASCII text, while still allowing for international characters, such as Chinese characters. As of the mid 2020s, UTF-8 is one of the most popular encoding systems.
UTF-8 is a compromise character encoding that can be as compact as ASCII (if the file is just plain English text) but can also contain any unicode characters (with some increase in file size). UTF stands for Unicode Transformation Format. The '8' means it uses 8-bit blocks to represent a character.
