The category of character sets includes articles on specific character encodings (see the article for a precise definition). It includes those used in computer science (coded character sets (also known as character sets (this term should not be used anymore^{[ according to whom?]}) or code pages), character encoding forms, character encoding schemes) and those that use non-numeric, pre-digital codes, such as electrical impulses. This category does not include unencoded character repertoires like the Windows Glyph List 4 or any of the articles in List of alphabets.

Articles pertaining to character encoding in general, or encoding in general, may be found in the parent categories, Category:Character encoding and Category:Encodings.

Much of this terminology is standardized in Unicode Technical Report #17 and ISO/IEC TR 15285:1998.
