Description

U+0D57, known as the Malayalam Au Length Mark, is a specialized Unicode character used primarily in the digital representation of the Malayalam script, an abugida writing system predominantly utilized in the Indian state of Kerala and among Malayali-speaking communities. This particular character serves a vital role in determining the length of vowels and in indicating the correct pronunciation of words by using diacritical marks. The Malayalam Au Length Mark, as part of the broader Unicode Standard, ensures that text is accurately represented across various digital platforms and applications, maintaining linguistic integrity for users of the Malayalam script.

How to type the symbol on Windows

Hold Alt and type 3415 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+0D57. 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+0D57 to binary: 00001101 01010111. 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 10110101 10010111
