About ASCII
ASCII (American Standard Code for Information Interchange) is a 7-bit character set with 128 values (0–127).
Control characters (0–31 and 127): Non-printable characters like NUL, TAB, LF (line feed), CR (carriage return), ESC, DEL.
Printable characters (32–126): Space, digits (0–9), uppercase (A–Z), lowercase (a–z), and punctuation.
ASCII does not include accented characters (ü, é), currency symbols (€), or emoji (🙂). For those, use UTF-8 byte encoding or the Hex converter.
