Description

U+1FDF is the Unicode character code for "GREEK DASIA AND PERISPOMENI", a rare and unique combination of two ancient Greek scripts. In digital text, this character is typically used in specialized contexts, such as typography, linguistics, and historical studies, to represent these antiquated scripts accurately. The Greek Dasia and Perispo meni are from the Cyprus syllabary, a precursor to the modern Greek alphabet, which was used on the island of Cyprus around 1200 BCE. These scripts were inscribed on clay tablets for record-keeping purposes, making them an essential part of the history of written language. Today, the usage of this character is mainly limited to academic or professional contexts that require the accurate representation of ancient Greek scripts. As a result, U+1FDF plays a vital role in preserving and understanding the linguistic and cultural heritage of these early forms of writing.

How to type the symbol on Windows

Hold Alt and type 8159 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+1FDF. 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+1FDF to binary: 00011111 11011111. 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 10111111 10011111
