Letterlike symbols are a set of characters that represent letters or words, but are not actually part of the alphabet. These symbols are designed to look like letters or words, but have their own unique meanings and uses in various contexts. One of the most common examples of a letterlike symbol is the copyright symbol (©), which is used to indicate ownership of a creative work. Other examples include the trademark symbol (™), which is used to indicate ownership of a brand or product name, and the registered trademark symbol (®), which is used to indicate that a trademark is registered with the appropriate authorities.
Other letterlike symbols include the degree symbol (°), which is used to indicate temperature or angle measurements, and the plus-minus symbol (±), which is used to indicate a range of values. The section symbol (§) is used to indicate a specific section or topic within a larger document, while the dagger (†) and double dagger (‡) symbols are used to indicate footnotes or other types of annotations.
