Description

The Unicode character U+2381, known as the Continuous Underline Symbol, holds a significant role in digital typography. It is often employed to denote an uninterrupted underline that spans across multiple lines of text, providing a consistent visual cue for the reader. This symbol is particularly valuable in instances where cohesion and uniformity are crucial, such as legal documents, technical manuals, or other formal contexts. Its use can facilitate easier navigation and comprehension, serving as a marker for hyperlinks or index entries within lengthy texts. Despite its relatively niche application, the Continuous Underline Symbol plays an important part in enhancing the legibility and accessibility of digital content across various platforms and devices, demonstrating the importance of thorough typographic design considerations even in seemingly minor details.

How to type the symbol on Windows

Hold Alt and type 9089 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+2381. 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+2381 to binary: 00100011 10000001. 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:
    11100010 10001110 10000001
