Description

The Unicode character U+00AE, also known as the REGISTERED SIGN (®), is a significant typographical symbol used primarily in digital text for legal documentation and intellectual property matters. Its role is to denote that a piece of information is protected under a copyright or trademark registration. This character is particularly common in official titles, brand names, and logos that have been legally registered. In linguistic and cultural contexts, the REGISTERED SIGN serves as an essential tool for preventing misrepresentation and confusion, ensuring proper attribution of ownership for ideas, products, or services within digital text. This helps maintain intellectual property rights in the digital realm, contributing to clear communication and a visually pleasing experience for readers. The REGISTERED SIGN is part of the Latin-1 Supplement Unicode block, a versatile collection of characters (U+0080 to U+00FF) that serve various text formatting and typography purposes. This character can be found in the range between 174 and 174 in decimal code points or 00AE in hexadecimal notation. The Latin-1 Supplement block was designed as an extension of the basic Latin character set to accommodate additional symbols that enhance the readability and overall appearance of text documents.

How to type the ® symbol on Windows

Hold Alt and type 0174 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+00AE. 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+00AE to binary: 10101110. 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:
    11000010 10101110
