Step 1: Determine the UTF-8 encoding bit layout
The character ٤ has the Unicode code point U+0664. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 10xxxxxx
Where thexare 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+0664 to binary:
00000110 01100100. 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:
11011001 10100100

Description
U+0664 is the Unicode character code for the Arabic numeral digit "Four" (أربع). In digital texts, this character represents the number four within the Arabic numeral system, which is widely used across many languages and cultures. Arabic numerals are a decimal system, meaning they consist of ten distinct symbols (0-9) to represent values, including U+0664 representing the value of four. This numeral digit is derived from the ancient Brahmi numeral system and was further developed by Islamic mathematicians in the Middle Ages. Today, U+0664 plays a vital role in various fields such as mathematics, computing, and programming languages, where it helps communicate numerical information accurately across multiple cultures and scripts.
