Description

U+1F3D is a specialized character in the Unicode standard representing the Greek capital letter Iota with Dasia and Oxia (Greek: Ι). This character plays a significant role in digital text, particularly in fields such as linguistics, computer science, and typography. The Greek alphabet has been widely used for centuries, serving as the basis for several other writing systems including Latin, Cyrillic, and Hebrew. In the context of Unicode, U+1F3D is essential for accurate representation of ancient or modern Greek text in digital environments, ensuring that the nuances of language and cultural heritage are preserved. The Dasia and Oxia symbols refer to two historical diacritics used in early forms of the Greek alphabet.

How to type the symbol on Windows

Hold Alt and type 7997 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+1F3D. 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+1F3D to binary: 00011111 00111101. 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 10111100 10111101
