Description

The Unicode character U+2977, known as LEFTWARDS ARROW THROUGH LESS-THAN, is a specialized symbol used in digital text to represent a specific mathematical operation or function. In mathematical expressions, it denotes an action of taking the lesser value between two compared elements. The symbol's unique design, which combines a leftward arrow with a less-than sign, visually conveys this comparison operation at a glance. While its usage is quite niche and primarily found in advanced mathematical contexts, it plays a crucial role in certain calculations and algorithms, particularly within programming languages and computer science. Despite not having any direct cultural, linguistic, or technical significance beyond its specific purpose, the LEFTWARDS ARROW THROUGH LESS-THAN symbol demonstrates the flexibility and expressiveness of Unicode in representing a wide range of characters and concepts.

How to type the symbol on Windows

Hold Alt and type 10615 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+2977. 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+2977 to binary: 00101001 01110111. 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 10100101 10110111
