Description

U+06F1, also known as EXTENDED ARABIC-INDIC DIGIT ONE, is a character in the Unicode standard that represents the numeral '1' in extended Arabic-Indic script. This digit holds significant importance in digital text, especially in regions where the extended Arabic-Indic numerals are used for representing numbers in text formats. The extended Arabic-Indic numerals were designed to address the shortcomings of the original Arabic numeral system, specifically, its limited range and compatibility with other writing systems. U+06F1, as part of this numeral system, enables precise representation of numerical values in digital text for languages that use the extended Arabic-Indic script, enhancing readability and reducing confusion across different cultures and regions. It is widely used in software applications, web content, and document formatting to ensure accurate and clear communication of numerical data.

How to type the ۱ symbol on Windows

Hold Alt and type 1777 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character ۱ has the Unicode code point U+06F1. 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+06F1 to binary: 00000110 11110001. 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:
