Step 1: Determine the UTF-8 encoding bit layout
The character ΰ has the Unicode code point U+1FE3. 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+1FE3 to binary:
00011111 11100011. 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:
11100001 10111111 10100011

Description
The Unicode character U+1FE3 represents the Greek letter "Upsilon with Dialytika and Oxiac", a variant of the Greek letter Upsilon (Υ, U+0379). It is rarely used in digital text and primarily found in specialized typography or academic texts dealing with historical or esoteric aspects of the Greek language. In its standard form, Upsilon is an uppercase letter that is equivalent to the English "U". However, U+1FE3 adds two diacritical marks, Dialytika ( diaeresis) and Oxiac (stroke), which modify its pronunciation in certain Greek dialects or historical texts. In digital text, such as websites or word processing documents, these characters are encoded using Unicode to ensure accurate representation across different platforms and devices. Overall, the use of U+1FE3 is relatively infrequent and mainly serves a purpose for specific linguistic research or historical documentation.
