Description

The Unicode character U+2EE1, known as the CJK Radical Head (also referred to as "CJK Radical 1"), plays a crucial role in Chinese character composition. In digital text, it serves as an indicator for the radical structure of complex characters in traditional Chinese characters. It is typically used in conjunction with the CJK Radicals (U+2E80–U+2EFF) to represent the core or primary component of a character. The use of these radicals assists readers in understanding the meaning and pronunciation of the characters, as well as their etymology. U+2EE1 is primarily found in Chinese dictionaries, glossaries, and texts where the accurate representation of traditional characters is essential. Its significance extends to various fields such as linguistics, education, and computer science, particularly in the development of software that handles Chinese text. Overall, U+2EE1 contributes to the richness of written Chinese by providing a clear and systematic way to represent complex characters and their radical structures.

How to type the symbol on Windows

Hold Alt and type 12001 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+2EE1. 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+2EE1 to binary: 00101110 11100001. 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 10111011 10100001
