Description

How to type the 🪡 symbol on Windows

Hold Alt and type 129697 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+1FAA1. In UTF-8, it is encoded using 4 bytes because its codepoint is in the range of 0x10000 to 0x10ffff.

    Therefore we know that the UTF-8 encoding will be done over 21 bits within the final 32 bits and that it will have the format: 11110xxx 10xxxxxx 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+1FAA1 to binary: 00000001 11111010 10100001. 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:
