title: "-" shown diff between sublime and IDEA
body: <p>I copy a code from a pdf . it is similar with "+-----+"</p>
  
  <p>The strange thing is when it copied to Ultraedit or Textedit or Sublime (Mac notebook) the "-" would always not been shown.</p>
  
  <pre><code>By UE Hex mode, the binary is :C2 AD, and shown as a "A with a ^ above";
  and if copied to IDEA, it would been shown correctly as "+-----+";
  if in sublime ,it would disappear, just shown as "++".
  </code></pre>
  
  <p>But use javac to compile and run it ,two software would both print to file "-" at the same apperance.</p>
  
  <p>The problem is :
  Why same item copied to different software showned diff appearance? Is it the Software's coding setting diffs? but I checked IDEA and sublime and UE were all UTF-8.</p>
