Description

The Unicode character U+064F, known as the Arabic Damma, is a crucial component of the Arabic script used for writing in multiple languages across North Africa and West Asia. In digital text, it serves as one of the four vertical marks employed to connect or separate words within a sentence or paragraph, demonstrating its essential role in maintaining text readability and coherence. This particular character is specifically utilized after specific Arabic letters (such as "ف", "ق", "ص" and "ک") to either create a new word or indicate vowel patterns. The usage of U+064F reflects the importance of diacritical marks in the Arabic language, which are essential for conveying meaning, grammatical structure, and phonetic pronunciation.

How to type the ُ symbol on Windows

Hold Alt and type 1615 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+064F. 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+064F to binary: 00000110 01001111. 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:
