Description

The Unicode character U+1D51 represents the "MODIFIER LETTER SMALL ENG". It is primarily used in digital text to modify the preceding character, often in specialized linguistic or technical contexts. Although not a widely known symbol, its utility lies in its ability to change the properties of the immediately adjacent letter, such as altering its case, diacritic marks, or tone. This functionality can be crucial in certain languages or disciplines that rely on subtle variations in character forms for correct expression and understanding. However, given its specialized usage, it might not have a significant cultural, linguistic, or technical context outside of specific niche applications. Overall, U+1D51 is an essential tool for precise typography and communication in certain fields, emphasizing the value of Unicode's comprehensive character set for global digital text representation.

How to type the symbol on Windows

Hold Alt and type 7505 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+1D51. 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+1D51 to binary: 00011101 01010001. 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 10010001
