Description

The character U+0871, or ARABIC LETTER ALEF WITH ATTACHED TOP RIGHT FATHA, is an important symbol in Arabic typography and digital text. It represents the initial consonant in several Arabic words, and its presence serves to distinguish it from other letters, such as Alif or Alef with different diacritical marks. This particular letter features a special diacritical mark called Fatha, which indicates a short vowel sound "a" in the word. This character is essential for accurate representation of Arabic text in digital platforms and helps maintain the linguistic integrity of written communication. The Fatha mark on Alef is culturally significant as it indicates an important aspect of Arabic phonetics, which heavily rely on diacritical marks to convey meaning. In terms of technical context, ARABIC LETTER ALEF WITH ATTACHED TOP RIGHT FATHA is a Unicode character that ensures proper encoding and display in digital systems, contributing to the standardization of Arabic typography worldwide.

How to type the symbol on Windows

Hold Alt and type 2161 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+0871. 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+0871 to binary: 00001000 01110001. 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 10100001 10110001
