Description

The Unicode character U+09D7 is known as the Bengali Au Length Mark, a vital glyph in the Bengali script used for digital text representation. This character serves a crucial role in Bengali typography by helping to accurately distinguish word lengths and syllable divisions. In the Bengali language, which is primarily spoken in Bangladesh and the Indian state of West Bengal, vowels can be nasalized or oral, lending additional phonetic nuances. The Au Length Mark assists in visually conveying these distinctions to typographers, writers, and readers, ensuring clarity and proper pronunciation. Additionally, the character adheres to Unicode standards for consistent encoding across various digital platforms and applications.

How to type the symbol on Windows

Hold Alt and type 2519 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+09D7. 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+09D7 to binary: 00001001 11010111. 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 10100111 10010111
