Description

The Unicode character U+1F45 is known as "GREEK SMALL LETTER OMICRON WITH DASIA AND OXIA." In digital text, this symbol represents a modified form of the Greek letter omicron (ο), which is used in Greek orthography. Specifically, it features two diacritics: the daseia and the oxia. The daseia is an ancient horizontal stroke that has been added to the letter as a way of indicating a long vowel sound, while the oxia is a vertical stroke used to differentiate certain words or grammatical cases. In modern usage, this character may be found in typography and text formatting for historical documents, linguistic studies, or cultural works that require accurate representation of ancient Greek texts.

How to type the symbol on Windows

Hold Alt and type 8005 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+1F45. 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+1F45 to binary: 00011111 01000101. 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:
