Description

U+3014 is the Unicode character code for the Left Tortoise Shell Bracket (〚), a less commonly used typographic symbol primarily found in digital text. This unique bracket is part of the Japanese Industrial Standard (JIS) X 0213:2000, and is employed in the Kana-based kakko notation system for representing numbers and dates in written Japanese. Its name, "Left Tortoise Shell Bracket," stems from its resemblance to a tortoise shell when viewed from the left side. Although not as prevalent as other brackets, U+3014 plays a significant role in the accurate rendering of complex text structures within the Japanese language and ensures proper formatting for numbers and dates. It is essential to include this character in Unicode and typography discussions, as it contributes to maintaining linguistic accuracy and cultural authenticity in digital communication.

How to type the symbol on Windows

Hold Alt and type 12308 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+3014. 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+3014 to binary: 00110000 00010100. 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:
