Description

The Unicode character U+23B1, known as the Upper Right or Lower Left Curly Bracket Section, serves a specific role within digital typography. It is primarily used to denote sections or regions in mathematical expressions, computer programming, and technical documentation. This character's primary function is to create an enclosure for content, similar to other curly brackets, but with its unique orientation of the curved shape pointing either upward to the right or downward to the left. While it may not be as commonly used as other symbols, U+23B1 holds importance within specific fields and applications. For example, in mathematical notation, it can help to distinguish different types of sets or intervals, providing clarity in complex equations. In programming languages, it can indicate a new scope or a section of code that should be read and executed separately from the surrounding context. Although U+23B1 may not have a significant presence in popular culture or language, its use is essential in specialized areas such as computer science, mathematics, and other technical disciplines where precision and clarity in representation are crucial. By understanding the role of this character within these contexts, users can appreciate its value and ensure accurate communication in their digital text.

How to type the symbol on Windows

Hold Alt and type 9137 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+23B1. 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+23B1 to binary: 00100011 10110001. 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:
    11100010 10001110 10110001
