Description

The character U+1FB7, Greek Small Letter Alpha with Perispomeni and Ypogegrammeni, is a rare and specialized symbol in the Unicode Standard, which plays a significant role in digital text encoding for the Greek language. In typography, it represents an early form of the Greek letter 'alpha' that was used to indicate vowel length and accentuation in ancient Greek manuscripts. Its perispomeni (overdot) and ypogegrammeni (underdot) markings help differentiate long and short vowels within words, aiding in the accurate pronunciation and understanding of text. This specific character is not commonly used in modern Greek typography but holds cultural and historical significance for linguists, historians, and scholars studying ancient Greek literature and languages.

How to type the symbol on Windows

Hold Alt and type 8119 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+1FB7. 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+1FB7 to binary: 00011111 10110111. 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 10111110 10110111
