title: Remove a sub string in a Korean string in C++
body: <p>I have a Korean string: "태권소녀 1". And now I want to remove a substring, " 1" (a space and '1' character). How can I do it in C++?</p>
  
  <p>With the English string it works ok, but I cannot do it with Korean yet.</p>
  
  <p>Thank you so much if you can give me some ideas.</p>
