c++ boost判断一个字符串中是否含有汉字的代码

 

 
  for 
   ( 
  set 
  < 
  string 
  > 
  ::iterator it 
  = 
  institutionnames.begin();it 
  != 
  institutionnames.end();it 
  ++ 
  )
 {
  wstring wtemp 
  = 
  strp.String2Wstring( 
  * 
  it);
  boost::wregex wreg(L 
  " 
  [\u4e00-\u9fa5] 
  " 
  );
  boost::wsmatch m;
  wstring::const_iterator mybegin 
  = 
  wtemp.begin();
  wstring::const_iterator myend 
  = 
  wtemp.end();
  
   
  if 
   (wtemp.size() 
  > 
  3 
  )
  {
    
  if 
   (boost::regex_search(mybegin,myend,m,wreg))
           {
      standardwps.push_back( 
  * 
  it);

           }
   
  }

 }
