Description

The Unicode character U+2F7D, known as the "Kangxi Radical And", is an advanced typographical symbol that plays a significant role in traditional Chinese text processing. This character serves as a logical operator to denote "and" in the Kangxi Dictionary system, which was created during the Qing Dynasty in China by the famous scholar Lei Gengyu. In this context, it is used to categorize Chinese characters according to their structural components or radicals, thereby facilitating their classification and lookup in the dictionary. The usage of U+2F7D is particularly prevalent in linguistic and cultural research areas that deal with traditional Chinese language systems and ancient texts. In digital text processing, the Kangxi Radical And character can be applied to help with the organization and retrieval of information. Its use in modern technology, however, is limited due to the shift towards simplified Chinese characters in mainland China. Nevertheless, its historical significance and cultural context make it an important character for those studying or working with traditional Chinese text.

How to type the symbol on Windows

Hold Alt and type 12157 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+2F7D. 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+2F7D to binary: 00101111 01111101. 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 10111101 10111101
