Description

The Unicode character U+1D55, known as the Modifier Letter Small Bottom Half O, is a specialized typographical symbol used primarily in phonetic transcription systems such as the International Phonetic Alphabet (IPA) and the ALA-LC system. Its role is to denote a specific modification of a base letter by combining with it to create a new sound or pronunciation guide. The Modifier Letter Small Bottom Half O is used in conjunction with various letters, including "o," to form distinct phonetic distinctions and facilitate accurate pronunciation representation. In digital text, it helps bridge linguistic gaps across different languages and dialects, enabling clearer communication and better understanding of spoken sounds. While this character may not be as widely recognized or utilized in everyday text, it holds significant importance for professionals working with phonetics, linguistics, and language learning.

How to type the symbol on Windows

Hold Alt and type 7509 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+1D55. 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+1D55 to binary: 00011101 01010101. 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:
    11100001 10110101 10010101
