##判断中文的原理
注意: 中文与汉字CJKV 的区别。。日本,韩国,新加坡,古越南等国家也用汉字,但不是中文。。就像英文法文都使用拉丁字母,但拉丁语不等于英文。。
汉字Unicode区间4E00(19968)? 9FBF(40895) ,表意文字的区间,包括了多个国家的汉字,这个不是我们所需要的。。
GB
中文中的汉字又分为简体,繁体,3500常用字,而同是繁体汉字,香港--澳门--台湾--海外等地方使用的汉字也有一些区别。。同是简体汉字,中国大陆--马来西亚--新加坡--海外等地方使用的是有一些差别的。。
一般我们只需要的是大陆地区3500常用简体中文汉字(gb2312)。。
2312标准共收录6763个汉字,其中一级汉字3755个,二级汉字3008个;同时收录了包括拉丁字母、希腊字母、日文平假名及片假名字母、俄语西里尔字母在内的682个字符
3500常用文字在unicode编码中不是全部连续的。无法用一个正则来写出这个区间。

只能使用map装载这个3500汉字映射,再对输入文字进行配对判断。
