use double quote in ascii in comments
use double quote in ascii in comments

* was using the double quote in iso-8859-1, some editors
  complains about it. and there are not common way to
  specify the encoding (e.g. msvc 10 does not respect the
  encoding specified by the leading shebang line). so replace
  it with the double quote in ASCII.
