Description

The Unicode character U+2E30, known as the Ring Point, is a typographical symbol with limited use in digital text. Its primary role is to serve as a mark that represents a point of attachment or a connection point, often seen in engineering diagrams and technical illustrations. This character can be utilized to indicate the location where two or more elements are connected or joined together. The Ring Point's usage is mainly found in specialized fields such as mechanical design, electrical schematics, and other technical disciplines where precise representation of connections is crucial.

How to type the symbol on Windows

Hold Alt and type 11824 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+2E30. 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+2E30 to binary: 00101110 00110000. 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 10111000 10110000
