Step 1: Determine the UTF-8 encoding bit layout
The character ـ has the Unicode code point U+0640. 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+0640 to binary:
00000110 01000000. 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:

Description
The Unicode character U+0640, known as the Arabic Tatweel (Arabic: ٠), is a typographical element primarily used in digital text to represent a space that is often required for proper word separation and formatting in Arabic script. Unlike the Latin script where spaces are typically used to separate words, the Arabic language does not always require or use spacing in written form. However, the Tatweel character fulfills this role by providing a visual break between words without disrupting the flow of the text's right-to-left reading direction. This character is essential for maintaining the accuracy and readability of text in Arabic, particularly in digital environments such as websites, documents, and software applications. The Tatweel is widely used across various Arabic dialects and serves as a crucial tool for maintaining linguistic integrity within the digital realm, demonstrating the importance of Unicode's extensive character set in supporting global language diversity.
