Description

The Unicode character U+00DB, also known as LATIN CAPITAL LETTER U WITH CIRCUMFLEX (Û), is a significant typographical symbol often utilized in digital text for linguistic, cultural, and technical purposes. This character represents the Latin alphabet letter 'U' with a circumflex accent (^). In various Romance languages like French and Portuguese, it modifies the sound of specific words, such as softening the initial 'v' sound in the word "ouvrir" in French. Beyond its phonetic importance, U+00DB has cultural and historical significance, given its close ties to language evolution over time. For instance, in the development of many Romance languages, the circumflex accent often indicates a change in pronunciation or meaning from the base form. Moreover, this character plays a technical role in markup languages and text encoding systems for formatting and stylistic reasons. U+00DB belongs to the Latin-1 Supplement Unicode block (128 to 255), which extends the basic Latin character set to accommodate additional symbols essential for proper text formatting and presentation. Its use enhances the readability and visual appeal of digital content, spanning applications from professional documents to creative writing. This ensures clear communication and an aesthetically pleasing experience for readers across various cultures and contexts.

How to type the Û symbol on Windows

Hold Alt and type 0219 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character Û has the Unicode code point U+00DB. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of 0x0080 to 0x07ff.

    Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format: 110xxxxx 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+00DB to binary: 11011011. 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:
    11000011 10011011
