First of all I wonder what we want to achieve with this functions. I
understand that we want to avoid characters that can give us problems
with filenames on different systems.
On linux/unix I know of only one char: '/'
Of course there are others that is not usually used in filenames, like
'\n' and ';', but they are not really a problem.
On Win we probably have a problem with '\\' as well.
What about OS/2?
Anyway. If you could tell be which of the chars that this outputs
should not be used in filenames:
// begin test file
#include <cctype>
#include <iostream>
int main()
{
for (int i = 0; i < 256; ++i) {
int k = i & 0x7f; // strip 8th bit
if (!isgraph(k))
k = '_';
cout << "(" << i
<< ") Modified: `" << char(k) << "'" << endl;
}
}
// end test file
