统计字数
要准确地统计字数，可逐一将字符串转换为ASCII码，依据其值判断是为中文字符还是英文字符。0——127之间的为大小写字母及数字、半角标点符号、回车、换行等，中文字符的ASCII值则不在0——127之列了。这样，纯汉字的字数统计是很容易的，倒是英文的统计复杂，因为英文统计应以单词为单位，而要判断是否为单词并不是简单的事。我们可以这么处理：如果被检测的字符为大小写字母，则判断其后面的字符是否为一个单词的标志(如空格、标点符号、回车符等），如是，则判断为一个单词。
以下代码能较准确地统计出TextBox控件中的中、英文字数和数字字符数，并将全部字节数(含各种控制符如回车等)也统计出来。适用于中英文编排环境。
