Identify the actual copyright character
The Unicode character list identifies © as U+00A9 COPYRIGHT SIGN. It separately lists related characters such as the circled capital C and sound-recording copyright sign; visually similar symbols need not be the same encoded character. You can copy the actual © from this paragraph when that is the character you intend. This guide concerns typing and visual formatting, not determining rights in a work or permission to use a font.
Insert the sign in Word rather than constructing it from shapes
For supported desktop Word versions, Microsoft’s symbol insertion instructions describe Insert > Symbol > More Symbols and the Special Characters tab. The same instructions document Alt+Ctrl+C for the copyright sign. Menu and shortcut behavior should be checked against the application and keyboard you actually use. Keep the result as a text character when it belongs in an editable text line; drawing a circle around a letter creates a different editing workflow.
Match the symbol to the surrounding information
Put the sign beside the actual adjacent wording and inspect its apparent weight, height and space. Compare the whole line at its intended output size rather than enlarging the symbol alone. If a selected font cannot display the character, inspect a font with the required coverage rather than substituting an unrelated dingbat key and assuming it will copy correctly. Inter and Lora offer independent text comparisons. For a separate decorative caption, explore the homepage font-style generator; it creates copyable Unicode treatments and does not grant rights or supply a license for a typeface.
For a contrasting symbol workflow, the Harvey Balls guide explains a font that maps numeric input to rating drawings instead of inserting the copyright character.
Your questions, answered.
Do I need to install a copyright font to type ©?
No special family is required by the character itself. Use a font and application that support the actual copyright sign.
Does typing © tell me whether I may use a particular font?
No. Character insertion and the terms governing font software are separate questions. Consult the original font resource for its applicable terms.
