Inputting Non ASCII characters to scanf(“%s”)

Question

Is there a way one can issue non ascii hex characters to a scanf that uses %s ? I\'m trying to insert hexadecimal chars like \\x08\\xDE\\xAD and so

Answer 1

When you say 'to a scanf()', presumably there is other data than just this to be supplied. Would it work to have a program, perhaps a Perl or Python script, generate the data and write the non-ASCII characters to the standard input of your program? If you need standard input to appear like a terminal, then you should investigate expect which handles that for you. This is a common way of dealing with the problem.
