 Hi,
 When I used regex_replace function to replace whitespace character in one
 string, I found that another character(0xa0 in memory) was also replaced.

 The follow is my verification code:

 int main(int argc, _TCHAR* argv[])
 {
     boost::regex whitespace_re("\\s+");
     string instr = "a c d f";
     cout << "Before replace instr:" << instr << endl;
     instr = boost::regex_replace(instr, whitespace_re, "-");
     cout << "After replaced instr: " << instr << endl;

     string instr2 = "abcdef";
     instr2[0]= 0xa0;
     instr2[2]= 0xa0;
     cout << "Before replace instr2:" << instr2 << endl;
     instr2 = boost::regex_replace(instr2, whitespace_re, "-");
     cout << "After replaced instr2: " << instr2 << endl;
     return 0;
 }

 And the output is attached.
 Develop Environment:
