Description

The Unicode character U+002D, known as the HYPHEN-MINUS (hyphen-minus-u-002d), plays a significant role in digital typography. Primarily used to denote negative values or signs in numerical expressions, it is an essential component for distinction between positive and negative quantities in mathematical equations, textual divisions, and various forms of digital communication. In addition to its numerical context, the HYPHEN-MINUS also functions as a key part of compound word formation in certain languages, such as German, where it links multiple words together as a single concept, like "Ein-Zimmer-Wohnung" meaning "One-room apartment." Furthermore, it is used to represent subtraction in calculations and is often employed in formatting dates and URLs. The HYPHEN-MINUS belongs to the Basic Latin Unicode block (basic-latin), a crucial component of the Unicode system consisting of 128 essential characters spanning from U+0000 to U+007F. This range includes control codes and various special symbols indispensable for programming languages, text documents, and multiple applications across platforms and devices. The Basic Latin block serves as the foundation upon which many other Unicode blocks are built due to its importance in modern communication.

How to type the - symbol on Windows

Hold Alt and type 0045 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+002D. In UTF-8, it is encoded using 1 byte because its codepoint is in the range of 0x0000 to 0x007f.

    Therefore we know that the UTF-8 encoding will be done over 7 bits within the final 8 bits and that it will have the format: 0xxxxxxx
    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+002D to binary: 00101101. 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:
