Description

The Unicode character U+2F10, known as the Kangxi Radical Open Box, plays a significant role in the field of digital text, specifically within the realm of Chinese characters and their classification system. This symbol is an essential component of the Kangxi Dictionary (康熙字典), compiled by the famous Qing Dynasty scholar Lei Din-Tao during Emperor Kangxi's reign. The Kangxi Dictionary is a comprehensive reference work that categorizes Chinese characters according to their radicals, which are the basic components or strokes that form a character. Each radical has an open box symbol like U+2F10, and these symbols help users locate characters based on their structural components, rather than relying solely on their meanings. This character classification system is still widely used today in various Chinese dictionaries, language learning resources, and computer input methods, making the Kangxi Radical Open Box an indispensable tool for those studying or working with the Chinese written language.

How to type the symbol on Windows

Hold Alt and type 12048 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+2F10. 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+2F10 to binary: 00101111 00010000. 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 10111100 10010000
