Control codes are shown as Unicode control pictures (␀ ␊ ␡). Caret notation is how terminals echo them: Ctrl plus the character 64 positions higher, so ^C is 3 and ^[ is ESC. \e is a GNU extension; portable C writes \033 or \x1b. Latin-1 (ISO 8859-1) leaves 128-159 to C1 control codes, which Windows-1252 fills with printable characters such as € and curly quotes. Text that shows â€™ where ’ belongs is UTF-8 read as Windows-1252.
