When you use email, be sure to use the right encoding. I have emailed some company with the default encoding (which was Chinese simplified) on my computer. It turned out to be a disarster. My email of course turned out to be unrecognized characters since their default encoding is English. The HR people are apparently not brave enough to figure out what is going with it. They simply just discard it. It was a costly lesson.
