I am looking at filtering special characters out of strings to make XML export/reimport safer when the BIOS contains ugly DMI infos or when the user sets crazy custom object info strings.
We don't want to waste time with encoding, supporting ascii is enough in the vast majority of cases. Others invalid chars will be removed from the XML-exported strings. But libxml doesn't like most characters between 0 and 31. I could just use isprint() to check every character before export and only keep those between 32 and 127. But what about \n, \t, \r, \f which are before ? Do we want to allow them? Brice
