Description

The Unicode character U+1FE9 represents the Greek capital letter upsilon with macron (ΓreeceKAPITALLETTERUpsILONWITHMacRON). This specific symbol is used in digital text to denote a particular variant of the Greek letter upsilon, which is usually represented by the lowercase υ and uppercase Υ. The use of this character in linguistic contexts can be traced back to Ancient Greece, where it was used in various fields such as mathematics, science, and literature. In modern times, U+1FE9 is employed primarily for typographical purposes, including the creation of unique fonts and the representation of specific diacritical marks in Greek-related digital text.

How to type the symbol on Windows

Hold Alt and type 8169 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+1FE9. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    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 the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+1FE9 to binary: 00011111 11101001. Those are the payload bits.

  3. 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 10101001
