Description

The Unicode character U+1C57 is known as the "OL CHIKI DIGIT SEVEN" and is used in the Ol Chiki script, an indigenous writing system created by Dr. Ranchhodkumar Pandya for the Adi people of Arunachal Pradesh, India. The Ol Chiki script was developed in 1964 to facilitate literacy among this tribal group, and its usage has since expanded beyond the Adi community. U+1C57, along with other characters in the Ol Chiki block (U+1C50-U+1C7F), plays a crucial role in transcribing the Adi language, which belongs to the Sino-Tibetan family and is spoken by over one million people in northeastern India. The digit seven represents the numeral value of "seven" in the Ol Chiki script, enabling accurate numerical representation and calculation within the language system.

How to type the symbol on Windows

Hold Alt and type 7255 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+1C57. 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+1C57 to binary: 00011100 01010111. 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:
    11100001 10110001 10010111
