Description

U+1D45 is the Modifier Letter Small Alpha character, a rarely used Unicode glyph that serves as a typographical component for creating new alphabetic characters in digital text. Its primary role lies in the creation of special alphabets or extended character sets for various linguistic or technical applications. Though it is not widely utilized, the Modifier Letter Small Alpha has been employed in some niche areas such as phonetics transcription, where it is used to modify existing characters and adapt them to specific pronunciation systems. This Unicode character contributes to the diversity and flexibility of written language and remains an essential tool for typographers and linguists working with specialized alphabets or character sets.

How to type the symbol on Windows

Hold Alt and type 7493 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+1D45. 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+1D45 to binary: 00011101 01000101. 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 10000101
