为此以及将来的参考：

\0 – Null character (that is a zero after the slash)
\\ – Backslash itself.  Since the backslash is used to escape other characters, it needs a special escape to actually print itself.
\t  – Horizontal tab
\n – Line Feed
\r  – Carriage Return
\”  – Double quote.  Since the quotes denote a String literal, this is necessary if you actually want to print one.
\’  – Single Quote.  Similar reason to above.
