Description

The Unicode character U+2E9F, known as CJK RADICAL MOTHER, is a unique typographic element predominantly found in the Chinese script. In digital text, it serves as a radical in the organization of Chinese characters and assists in their classification for dictionary purposes. This role is crucial because Chinese characters are composed of multiple components or radicals that together form a complete character. The CJK RADICAL MOTHER, specifically, is one of the 214 primary radicals used in the Kangxi Dictionary, which was compiled during the early Qing Dynasty and remains influential in modern Chinese linguistic study. Although its usage might be less prevalent in contemporary digital text due to the shift toward simplified characters, understanding the CJK RADICAL MOTHER remains essential for scholars of classical Chinese literature and language experts.

How to type the symbol on Windows

Hold Alt and type 11935 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+2E9F. 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+2E9F to binary: 00101110 10011111. 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 10111010 10011111
