Step 1: Determine the UTF-8 encoding bit layout
The character ⤈ has the Unicode code point U+2908. 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+2908 to binary:
00101001 00001000. 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 10100100 10001000

Description
The Unicode character U+2908, known as the Downwards Arrow with Horizontal Stroke, is a symbol that primarily serves a technical function in digital text. In mathematical and scientific notation, this character is commonly used to indicate a decrease or reduction in value. It can also represent a negative value or a downward-facing arrow, often used to denote an element moving downwards or towards a lower position. While it may seem similar to the common "downward arrow" (U+2193), the inclusion of a horizontal stroke differentiates U+2908 and gives it specific technical significance in certain contexts. The Downwards Arrow with Horizontal Stroke plays an important role in typography when precise mathematical or scientific expressions are needed, as its presence can prevent ambiguity and misinterpretation.
