Thank Christoph for your information.
I don't program in C at all, but Java. Although I can make a way to call the C library function from Java, it isn't suitable
solution, I believe.
I only desire to find out all the type of characters at the present time so that I can strip out any potential problem sources
in text. Who know what characters a user will enter.
