Description

The Unicode character U+0887, known as ARABIC BASELINE ROUND DOT, plays a vital role in the Arabic typography system. It is primarily used to indicate the presence of a diacritical mark or vowel sign above a base letter in Arabic text. In digital text, it acts as a visual anchor for the overlay of these diacritics and vowel signs, ensuring proper rendering and readability of the text by maintaining an accurate baseline alignment. U+0887 is essential to the accurate representation of Arabic script, which relies on these marks to convey specific phonetic values, grammatical features, or to denote long vowels. The use of this character contributes significantly to preserving and promoting the rich linguistic heritage of the Arabic language in digital environments.

How to type the symbol on Windows

Hold Alt and type 2183 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+0887. 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+0887 to binary: 00001000 10000111. 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:
    11100000 10100010 10000111
