Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+2001. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 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+2001 to binary:
00100000 00000001. 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:
11100010 10000000 10000001

Description
The Unicode character U+2001 is known as the EM Quad. It is a non-printing control character used to align text in digital documents. In typesetting, it serves as a form of layout control, assisting in the precise positioning and formatting of elements within a document. This includes adjustments for spacing, alignment, and pagination. Its usage is most commonly observed in professional publishing and desktop publishing environments where precision is crucial. Despite its significance in text layout, U+2001 EM Quad does not have any visual representation on screen or print. It is purely a behind-the-scenes character that impacts the look and feel of text without being seen itself.
