Unicode control characters: Standards, Category "Cc" control codes (C0 and C1) & Unicode introduced separators

Many Unicode characters are used to control the interpretation or display of text, but these characters themselves have no visual or spatial representation. For example, the null character (U+0000 NULL) is used in C-programming application environments to indicate the end of a string of characters. In this way, these programs only require a single…
