Description

U+1C7A, or OL CHIKI MU-GAAHLAA TTUDDAAG, is a unique Unicode character with a significant role in digital text. It is part of the Ol Chiki script, an abugida developed by the indigenous Sentinelese people of North Sentinel Island in the Andaman Islands, India. This writing system was created to represent their language, which has no known written form prior to its creation. U+1C7A specifically represents the phoneme /t/ when followed by a vowel, making it crucial for accurate transcription and communication of the Sentinelese language in digital text. The Ol Chiki script is not only culturally significant but also plays a vital role in linguistic preservation and future documentation efforts for this isolated community.

How to type the symbol on Windows

Hold Alt and type 7290 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+1C7A. 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+1C7A to binary: 00011100 01111010. 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 10111010
