C++中获取汉字拼音首字缩写/全拼及生僻字的处理

　　最近一直在修改关于搜索不到生僻字的问题，最后得出结论：对生僻字的处理，办法只有一个，建立一个字库，然后查表找。

　　可以参考一下：http://download.csdn.net/detail/lshlwy/8920047，枚举了两万多的汉字和拼音音调，直接去搜就好了。

1、关于生僻字的处理，加载一个汉字库，然后库中查找。（仅适用于生僻字，频繁查询字库文件，会非常的慢）对于这种循环查询的方法，可能会把程序变慢，匹配度一般。

 1 　　　　　　　 bool existFlag = false;
 2             if (firstPY.Find(strLowName) == -1 && util::existChinese(util::cStringToString(firstPY, CP_ACP)))//判断获得的首字拼音中是否还存在汉字，如果存在，说明有生僻字。
 3             {
 4                 std::vector<std::string>  specialCharaterPy;
 5                 module::getMiscModule()->GetSentencePinyin(util::cStringToString(RealName, CP_ACP), specialCharaterPy);//这里是查找汉字库，返回全拼。
 6                 CString Namepy;
 7                 Namepy = util::stringToCString(specialCharaterPy.at(0));
 8                 int  count = 0;
 9                 int  findPos = 0;
10                 int  startPos = 0;
11                 for (int i = 0; i < sShortName.GetLength(); i++)
12                 {
13                     findPos = Namepy.Find(sShortName[i], startPos); 
14                     if (findPos == -1)
15                     {
16                         break;
17                     }
18                     else
19                     {
20                         count++;
21                         startPos = findPos + 1;//从查找到位置后+1继续寻找
22                     }
23                 }
24                 if (count != 0 && count == sShortName.GetLength())
25                 {
26                     existFlag = true;
27                 }
28             }

　2.生僻字的存储跟普通的汉子有所区别，贴一个找到汉字拼音缩写的代码（无法查找到生僻字，生僻字的两个一个大于160，一个小于160，会返回原汉字）。

 1 std::string FirstLett(const char* strChs)

 3     static int li_SecPosValue[] = {

 5         3472, 3635, 3722, 3730, 3858, 4027, 4086, 4390, 4558, 4684, 4925, 5249

3.获取到汉字全拼的方法代码：（对于生僻字无法处理）

 4.关于字库的处理。(自行百度，效果更好)

 1 void GetHZpinyin(unsigned int hz, std::vector<std::string>& pinyinArr)
 2 {
 3     TCHAR ch = (TCHAR)hz;
 4     if (m_hz2PyObj == NULL)
 5     {
 6         m_hz2PyObj = new HZ2Pinyin;
 7         CString strAppPath = util::getAppPath();
 8         CString strDataFile = _T("hzpinyin.dat");
 9         std::string strFile = util::cStringToString(strAppPath + strDataFile);
10         m_hz2PyObj->LoadData(strFile);
11     }
12 
13     m_hz2PyObj->ObtainPinyin(hz, pinyinArr);
14 }
void ObtainPinyin(unsigned int word, std::vector<std::string>& pinyinArr)
{
    if (m_wordMap.empty())
    {
        return;
    }
    std::pair<HZ2PINYINMAP::iterator, HZ2PINYINMAP::iterator> iterRange = m_wordMap.equal_range(word);
    HZ2PINYINMAP::iterator pos = iterRange.first;
    HZ2PINYINMAP::iterator posEnd = iterRange.second;
    for (; pos != posEnd; ++pos)
    {
        pinyinArr.push_back(pos->second);
    }
}
