Description

The Unicode character U+2D99 is a rarely used typographical symbol known as the "Left Right Arrow" (⇉). It is not commonly utilized in digital text but has specific applications in programming, particularly when dealing with string manipulation or directional movement. In some contexts, it can serve as an indicator for reversing the order of elements within a sequence. Although not widely recognized in general typography, its presence in Unicode signifies potential functionality within specialized software or scripts requiring directional flow alteration.

How to type the symbol on Windows

Hold Alt and type 11673 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+2D99. 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+2D99 to binary: 00101101 10011001. 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:
