Description

The Unicode character U+1DD1 is known as the COMBINING UR ABOVE. It plays a significant role in digital typography, specifically within the realm of linguistic contexts that require diacritical marks for certain characters. This character is commonly utilized to combine with letters and symbols from languages like Thaana or for customizable textual embellishments. Despite its relatively low profile usage, it remains an essential tool for those who work with specialized scripts and typographic designs. Its application allows for greater flexibility in the manipulation of text, enhancing both visual appeal and readability across a range of language systems.

How to type the symbol on Windows

Hold Alt and type 7633 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+1DD1. 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+1DD1 to binary: 00011101 11010001. 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 10010001
