Step 1: Determine the UTF-8 encoding bit layout
The character ๐จ has the Unicode code point U+1D668. In UTF-8, it is encoded using 4 bytes because its codepoint is in the range of
0x10000
to0x10ffff
.
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 thex
are the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+1D668 to binary:
00000001 11010110 01101000
. Those are the payload bits.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:
11110000 10011101 10011001 10101000
