Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+2FFF. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 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+2FFF to binary:
00101111 11111111
. 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 10111111 10111111

Description
The Unicode character U+2FFF is known as the IDEOGRAPHIC DESCRIPTION CHARACTER ROTATION (IDCROT). It plays a vital role in digital text, particularly within the context of East Asian typography. This character enables the seamless rotation of ideographic characters during typesetting and layout processes in vertical writing systems, such as those found in Japanese, Korean, and traditional Chinese texts. Its primary function is to facilitate the correct positioning and alignment of individual glyphs within a block of text, ensuring that characters are displayed in their intended orientation when rendered in various digital platforms. As a crucial tool for designers and typographers working with East Asian scripts, U+2FFF significantly enhances the legibility and overall presentation quality of texts written in these languages.
