Description

The Unicode character U+20A1, also known as the COLON SIGN, is a valuable asset in digital typography. Primarily used to represent the symbol ':' in digital text, it plays a significant role in various contexts, including syntax for programming languages and data structures. One of its most notable uses is in HTML markup, where it serves as an essential part of hyperlinks and email addresses. The COLON SIGN's versatility extends to other applications such as data separators in command line arguments or as a delimiter in the widely-used comma-separated values (CSV) file format. While it may not hold the same cultural or linguistic significance as some other Unicode characters, its technical importance cannot be overstated, especially for those working with text processing and digital communication.

How to type the symbol on Windows

Hold Alt and type 8353 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+20A1. 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+20A1 to binary: 00100000 10100001. 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 10000010 10100001
