Questions tagged [special-characters]

Special characters (as they apply to programming) are language-specific reserved characters or symbols used to accomplish a specific task (e.g. wildcard characters, data type indicators, escape characters, etc).

Every character is special in its own way. When talking about "special characters" in a question, be specific. Do you mean ASCII symbols, Japanese kana, or Egyptian hieroglyphs?

For example, when working with Unicode, characters from exotic scripts aren't more "special", technically, than characters from the ASCII range. If you mean characters that you can't enter directly with an US PC keyboard, you should probably use the term "non-ASCII characters" and avoid this tag.
