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) 2 { 3 static int li_SecPosValue[] = { 4 1601, 1637, 1833, 2078, 2274, 2302, 2433, 2594, 2787, 3106, 3212, 5 3472, 3635, 3722, 3730, 3858, 4027, 4086, 4390, 4558, 4684, 4925, 5249 6 }; 7 static char* lc_FirstLetter[] = { 8 "a", "b", "c", "d", "e", "f", "g", "h", "j", "k", "l", "m", "n", "o", 9 "p", "q", "r", "s", "t", "w", "x", "y", "z" 10 }; 11 static char* ls_SecondSecTable = 12 "CJWGNSPGCGNE[Y[BTYYZDXYKYGT[JNNJQMBSGZSCYJSYY[PGKBZGY[YWJKGKLJYWKPJQHY[W[DZLSGMRYPYWWCCKZNKYYGTTNJJNYKKZYTCJNMCYLQLYPYQFQRPZSLWBTGKJFYXJWZLTBNCXJJJJTXDTTSQZYCDXXHGCK[PHFFSS[YBGXLPPBYLL[HLXS[ZM[JHSOJNGHDZQYKLGJHSGQZHXQGKEZZWYSCSCJXYEYXADZPMDSSMZJZQJYZC[J[WQJBYZPXGZNZCPWHKXHQKMWFBPBYDTJZZKQHY" 13 "LYGXFPTYJYYZPSZLFCHMQSHGMXXSXJ[[DCSBBQBEFSJYHXWGZKPYLQBGLDLCCTNMAYDDKSSNGYCSGXLYZAYBNPTSDKDYLHGYMYLCXPY[JNDQJWXQXFYYFJLEJPZRXCCQWQQSBNKYMGPLBMJRQCFLNYMYQMSQYRBCJTHZTQFRXQHXMJJCJLXQGJMSHZKBSWYEMYLTXFSYDSWLYCJQXSJNQBSCTYHBFTDCYZDJWYGHQFRXWCKQKXEBPTLPXJZSRMEBWHJLBJSLYYSMDXLCLQKXLHXJRZJMFQHXHWY" 14 "WSBHTRXXGLHQHFNM[YKLDYXZPYLGG[MTCFPAJJZYLJTYANJGBJPLQGDZYQYAXBKYSECJSZNSLYZHSXLZCGHPXZHZNYTDSBCJKDLZAYFMYDLEBBGQYZKXGLDNDNYSKJSHDLYXBCGHXYPKDJMMZNGMMCLGWZSZXZJFZNMLZZTHCSYDBDLLSCDDNLKJYKJSYCJLKWHQASDKNHCSGANHDAASHTCPLCPQYBSDMPJLPZJOQLCDHJJYSPRCHN[NNLHLYYQYHWZPTCZGWWMZFFJQQQQYXACLBHKDJXDGMMY" 15 "DJXZLLSYGXGKJRYWZWYCLZMSSJZLDBYD[FCXYHLXCHYZJQ[[QAGMNYXPFRKSSBJLYXYSYGLNSCMHZWWMNZJJLXXHCHSY[[TTXRYCYXBYHCSMXJSZNPWGPXXTAYBGAJCXLY[DCCWZOCWKCCSBNHCPDYZNFCYYTYCKXKYBSQKKYTQQXFCWCHCYKELZQBSQYJQCCLMTHSYWHMKTLKJLYCXWHEQQHTQH[PQ[QSCFYMNDMGBWHWLGSLLYSDLMLXPTHMJHWLJZYHZJXHTXJLHXRSWLWZJCBXMHZQXSDZP" 16 "MGFCSGLSXYMJSHXPJXWMYQKSMYPLRTHBXFTPMHYXLCHLHLZYLXGSSSSTCLSLDCLRPBHZHXYYFHB[GDMYCNQQWLQHJJ[YWJZYEJJDHPBLQXTQKWHLCHQXAGTLXLJXMSL[HTZKZJECXJCJNMFBY[SFYWYBJZGNYSDZSQYRSLJPCLPWXSDWEJBJCBCNAYTWGMPAPCLYQPCLZXSBNMSGGFNZJJBZSFZYNDXHPLQKZCZWALSBCCJX[YZGWKYPSGXFZFCDKHJGXDLQFSGDSLQWZKXTMHSBGZMJZRGLYJB" 17 "PMLMSXLZJQQHZYJCZYDJWBMYKLDDPMJEGXYHYLXHLQYQHKYCWCJMYYXNATJHYCCXZPCQLBZWWYTWBQCMLPMYRJCCCXFPZNZZLJPLXXYZTZLGDLDCKLYRZZGQTGJHHGJLJAXFGFJZSLCFDQZLCLGJDJCSNZLLJPJQDCCLCJXMYZFTSXGCGSBRZXJQQCTZHGYQTJQQLZXJYLYLBCYAMCSTYLPDJBYREGKLZYZHLYSZQLZNWCZCLLWJQJJJKDGJZOLBBZPPGLGHTGZXYGHZMYCNQSYCYHBHGXKAMTX" 18 "YXNBSKYZZGJZLQJDFCJXDYGJQJJPMGWGJJJPKQSBGBMMCJSSCLPQPDXCDYYKY[CJDDYYGYWRHJRTGZNYQLDKLJSZZGZQZJGDYKSHPZMTLCPWNJAFYZDJCNMWESCYGLBTZCGMSSLLYXQSXSBSJSBBSGGHFJLYPMZJNLYYWDQSHZXTYYWHMZYHYWDBXBTLMSYYYFSXJC[DXXLHJHF[SXZQHFZMZCZTQCXZXRTTDJHNNYZQQMNQDMMG[YDXMJGDHCDYZBFFALLZTDLTFXMXQZDNGWQDBDCZJDXBZGS" 19 "QQDDJCMBKZFFXMKDMDSYYSZCMLJDSYNSBRSKMKMPCKLGDBQTFZSWTFGGLYPLLJZHGJ[GYPZLTCSMCNBTJBQFKTHBYZGKPBBYMTDSSXTBNPDKLEYCJNYDDYKZDDHQHSDZSCTARLLTKZLGECLLKJLQJAQNBDKKGHPJTZQKSECSHALQFMMGJNLYJBBTMLYZXDCJPLDLPCQDHZYCBZSCZBZMSLJFLKRZJSNFRGJHXPDHYJYBZGDLQCSEZGXLBLGYXTWMABCHECMWYJYZLLJJYHLG[DJLSLYGKDZPZXJ" 20 "YYZLWCXSZFGWYYDLYHCLJSCMBJHBLYZLYCBLYDPDQYSXQZBYTDKYXJY[CNRJMPDJGKLCLJBCTBJDDBBLBLCZQRPPXJCJLZCSHLTOLJNMDDDLNGKAQHQHJGYKHEZNMSHRP[QQJCHGMFPRXHJGDYCHGHLYRZQLCYQJNZSQTKQJYMSZSWLCFQQQXYFGGYPTQWLMCRNFKKFSYYLQBMQAMMMYXCTPSHCPTXXZZSMPHPSHMCLMLDQFYQXSZYYDYJZZHQPDSZGLSTJBCKBXYQZJSGPSXQZQZRQTBDKYXZK" 21 "HHGFLBCSMDLDGDZDBLZYYCXNNCSYBZBFGLZZXSWMSCCMQNJQSBDQSJTXXMBLTXZCLZSHZCXRQJGJYLXZFJPHYMZQQYDFQJJLZZNZJCDGZYGCTXMZYSCTLKPHTXHTLBJXJLXSCDQXCBBTJFQZFSLTJBTKQBXXJJLJCHCZDBZJDCZJDCPRNPQCJPFCZLCLZXZDMXMPHJSGZGSZZQLYLWTJPFSYASMCJBTZKYCWMYTCSJJLJCQLWZMALBXYFBPNLSFHTGJWEJJXXGLLJSTGSHJQLZFKCGNNNSZFDEQ" 22 "FHBSAQTGYLBXMMYGSZLDYDQMJJRGBJTKGDHGKBLQKBDMBYLXWCXYTTYBKMRTJZXQJBHLMHMJJZMQASLDCYXYQDLQCAFYWYXQHZ"; 23 std::string result; 24 int H = 0; 25 int L = 0; 26 int W = 0; 27 UINT stringlen = strlen(strChs); 28 for (UINT i = 0; i < stringlen; i++) { 29 H = (UCHAR)(strChs[i + 0]); 30 L = (UCHAR)(strChs[i + 1]); 31 if (H < 0xA1 || L < 0xA1) { //这里出现生僻字问题 32 result += strChs[i]; 33 continue; 34 } 35 else { 36 W = (H - 160) * 100 + L - 160; 37 } 38 if (W > 1600 && W < 5590) { 39 for (int j = 22; j >= 0; j--) { 40 if (W >= li_SecPosValue[j]) { 41 result += lc_FirstLetter[j]; 42 i++; 43 break; 44 } 45 } 46 continue; 47 } 48 else { 49 i++; 50 W = (H - 160 - 56) * 94 + L - 161; 51 if (W >= 0 && W <= 3007) 52 result += ls_SecondSecTable[W]; 53 else { 54 result += (char)H; 55 result += (char)L; 56 } 57 } 58 } 59 60 return result; 61 }
