Description

The Unicode character U+300A, known as the Left Double Angle Bracket, primarily serves as a typographical symbol within digital texts. In most cases, this symbol is used to enclose a range of characters or numbers in various programming languages and markup languages. Its primary role is in denoting the inclusive range of elements between two points, often acting as an opening bracket for a series that ends with its counterpart, the Right Double Angle Bracket (U+300B). Despite its technical usage, there isn't any significant cultural or linguistic context attached to this character. The Left Double Angle Bracket is widely used in programming and coding due to its versatile nature and precise functionality. It is essential for creating complex structures in various digital texts such as HTML, CSS, JavaScript, etc., where the need arises to specify a range of values or elements.

How to type the symbol on Windows

Hold Alt and type 12298 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+300A. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+300A to binary: 00110000 00001010. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
    11100011 10000000 10001010
