Description

The Unicode character U+1DF5 represents the "COMBINING UP TACK ABOVE" symbol. This typographical element is utilized in digital text to modify uppercase letters by adding an upward pointing arrow or hook-like symbol above the letter. Its primary function is to enhance visual clarity and provide additional emphasis, particularly when used with initials or abbreviations in formal documents or titles. Although it may be considered as a stylistic embellishment, the COMBINING UP TACK ABOVE has some usage in specialized fields such as mathematics, computer science, and engineering, where it helps to distinguish between similar-looking characters or symbols, thus reducing ambiguity.

How to type the symbol on Windows

Hold Alt and type 7669 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+1DF5. 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+1DF5 to binary: 00011101 11110101. 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 10110111 10110101
