title: Strange Chinese characters mixed with English in RStudio
body: <p>I got strange Chinese characters whenever I try to install packages. For instance: </p>
  
  <blockquote>
    <p>installing the source package 態H</p>
  </blockquote>
  
  <p>I tried to searched this online and found a solution that says I can change the option, i.e. <code>options(useFancyQuotes = FALSE)</code></p>
  
  <p>This works perfectly. However, this only solve the problem temporarily, and those strange Chinese characters will show up again next time when I write a new program and install packages. So, I wonder if there's a way to solve this problem permanently? Can I do something so that the R will run <code>options(useFancyQuotes = FALSE)</code> automatically? Or, are there any other permanent solutions?</p>
  
  <p>Thanks!</p>
