Field defaults to the ansi character set 字段默认为ansi字符集。
The ascii and ansi character sets are constructed so that capital letters precede lowercase ones in sequence order Ascii和ansi字符集均按将大写字母排在小写字母前面的序列顺序进行构造。
The following example shows how to apply the strictest character mapping security to a platform invoke method definitions by specifying the ansi character set , disabling best fit mapping behavior , and throwing an exception on unmapped unicode characters 下面的示例说明如何通过指定ansi字符集、禁用最佳映射行为,并在遇到无法映射的unicode字符时引发异常,从而在平台调用方法定义上应用最严格的字符映射安全性。
