Description

The Unicode character U+330D, known as the SQUARE KARORII (極角), is a specialized typographical symbol primarily utilized in Japanese digital text. In the context of typography, it represents an ancient Chinese unit of angle measurement, equivalent to 2.5 degrees. It holds cultural significance in East Asian countries, particularly Japan and China, due to its historical usage in mathematical and scientific texts, as well as in traditional calendars for astronomical purposes. The SQUARE KARORII is also significant in the study of ancient Chinese astronomy, where it was employed in calculations related to celestial bodies' movements. In digital text, this character is commonly used in modern contexts such as programming and computing, often as a marker for specific angles or degrees within algorithms or mathematical equations.

How to type the symbol on Windows

Hold Alt and type 13069 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+330D. 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+330D to binary: 00110011 00001101. 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 10001100 10001101
