How to type the A symbol on Windows

Hold Alt and type 0065 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character A has the Unicode code point U+0041. In UTF-8, it is encoded using 1 byte because its codepoint is in the range of 0x0000 to 0x007f.

    Therefore we know that the UTF-8 encoding will be done over 7 bits within the final 8 bits and that it will have the format: 0xxxxxxx
    Where the x are the payload bits.

    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+0041 to binary: 01000001. 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:
