Description

The Unicode character U+1F2A represents the Greek capital letter Eta with psili and varia (ΓΠ). In the realm of digital text, this character is predominantly used in typography for representing the Greek alphabet or various linguistic applications. The Greek script has a rich cultural history, tracing its origins back to around 800 BC. The concept of "psili" refers to the dot above the letter, which is significant in terms of its pronunciation and identity within the Greek language. In linguistics, the Eta character plays a vital role as it constitutes one of the 24 letters of the Greek alphabet, serving as a foundation for many other characters due to its unique combination with psili and varia. The Unicode system enables accurate representation and encoding of this character in digital text, preserving its cultural and linguistic context while ensuring seamless integration across multiple platforms.

How to type the symbol on Windows

Hold Alt and type 7978 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+1F2A. 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+1F2A to binary: 00011111 00101010. 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 10101010
