Description

U+29CF, the Left Triangle Beside Vertical Bar, is a typographical character that plays a significant role in various applications within digital text. This Unicode character, also known as the "Left Triangle with Upwards Arrowhead Beside Vertical Line," serves primarily as a mathematical symbol or delimiter to represent a specific type of set or interval in mathematics and computer science. It is commonly used to denote an open-ended interval on the left side of a formula or equation, indicating that the value within the interval is less than but not equal to the specified bound. While this character is not widely used in everyday written language, it holds a crucial position in formal mathematical notation and coding systems, particularly when dealing with intervals, ranges, and data sets.

How to type the symbol on Windows

Hold Alt and type 10703 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+29CF. 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+29CF to binary: 00101001 11001111. 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 10100111 10001111
