In our material, we answer the questions: UTF-8 – what is it? What is it us for? That are the advantages and disadvantages of the standard? What is UTF-8 UTF-8 (Unicode Transformation Format, 8-bit) is an encoding system that works according to the Unicode standard. The Unicode library stores over a million symbols. Each of them is assign a unique code – a code point. For example, for “!” the code point is U+0021. UTF-8 converts Unicode symbols into computer text – binary strings. In addition, the encoding also works in the opposite direction: from binary strings to symbols.

UTF-8 is part of the Unicode family of encodings, each of which is unique. The peculiarity of UTF-8 is that it represents characters gambling data japan in single-byte units. One byte contains, in its simplest form, eight bits of information, which is reflect in the name of the encoding. What is character encoding for? Computers process information in the binary system. To understand a text message, they ne to process a sequence of zeros and ones.
For example, the English letter A is 01000001
This is not enough for a person to understand the text; he perceives data written using letters, numbers, and other symbols, and he will also visualize different segments ne to know the language in which the message is written. In order for the text transmitt by the computer to become accessible to the user, it is necessary to transform its numerical representation into a symbolic one.
The tool for transformation is encodings
Which contain a set of rules for converting one way of representing information into another. The computer speaks the language of bits buying house b and bytes. Information in the binary system is measur using bits. If the data volume reaches 8 bits, then for convenience of calculations a larger unit of measurement is us – a byte, follow by kilobytes, megabytes and gigabytes. Each character of the text is record in the computer system as a string of bits.
