Description

The Unicode character U+03CA, Greek Small Letter Iota with Dialytika, plays a significant role in the digital representation of ancient Greek text. It is primarily used to display the pronunciation of the Greek letter iota (Ι/ι) by marking it for elongated vowel sounds. In ancient Greek texts, the dialytika (also known as diaeresis) was employed to indicate that a vowel was long in pronunciation, and U+03CA follows this same function in digital typography. This character is invaluable for accurate representation of historical texts and preserving linguistic integrity in modern Greek typography. By including U+03CA in digital text, scholars, linguists, and typographers can maintain the authenticity of ancient Greek writings while making them accessible through modern devices and platforms.

How to type the ϊ symbol on Windows

Hold Alt and type 0970 on the numpad. Or use Character Map.

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

    The character ϊ has the Unicode code point U+03CA. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of 0x0080 to 0x07ff.

    Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format: 110xxxxx 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+03CA to binary: 00000011 11001010. 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:
