Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+200D. 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+200D to binary:
00100000 00001101
. 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 10001101

Description
The Unicode character U+200D (ZERO WIDTH JOINER) plays a pivotal role in the world of typography and digital text. As its name suggests, this character is essentially invisible in terms of appearance, but it serves as an indispensable tool for the manipulation of text. Its primary purpose is to join together characters from different scripts or sequences within a single text stream without causing any visible disruption or alteration to the displayed text. This feature is particularly useful in multilingual settings and has been instrumental in promoting the smooth flow of text when combining characters from languages that follow different writing systems, such as Arabic and Latin scripts. The ZERO WIDTH JOINER character facilitates the seamless integration of Unicode content, aiding in the preservation of the integrity of textual data while ensuring its compatibility across various platforms and devices. The importance of this seemingly inconspicuous character cannot be overstated, as it significantly contributes to the harmonious display and functionality of digital text on an international scale. In essence, the ZERO WIDTH JOINER acts as a quiet yet powerful ally in the ongoing quest for seamless intercultural communication through digital means.
