winapi的兩個函式：widechartomultibyte、multibytetowidechar。
int multibytetowidechar(
uint codepage, // code page
dword dwflags, // character-type options
lpcstr lpmultibytestr, // string to map
int cbmultibyte, // number of bytes in string
lpwstr lpwidecharstr, // wide-character buffer
int cchwidechar // size of buffer
);//將多個窄字元轉換成寬字元
需要用到的一些函式：cstring cxmlprocess::hextobin(cstring string)//將16進製制數轉換成2進製
cstring cxmlprocess::bintohex(cstring binstring)//將2進製數轉換成16進製制
int cxmlprocess::bintoint(cstring string)//2進製字元資料轉換成10進製整型
len += tempint*strint;
}return len;
}
utf-8轉換成gb2312先把utf-8轉換成unicode.然後再把unicode通過函式widechartomultibyte轉換成gb2312 wchar*
cxmlprocess::utf_8tounicode(char *ustart) //把utf-8轉換成unicode
char * cxmlprocess::unicodetogb2312(unsigned short udata) //把unicode 轉換成 gb2312
gb2312轉換成utf-8：先把gb2312通過函式multibytetowidechar轉換成unicode.然後再把unicode通過拆開unicode後拼裝成utf-8。
wchar * cxmlprocess::gb2312tounicode(char *gbbuffer) //gb2312 轉換成 unicode
char * cxmlprocess::unicodetoutf_8(wchar *unichar) // unicode 轉換成utf-8
例子：將gb2312轉換成utf-8的呼叫：
char * cxmlprocess::translatechartoutf_8(char *xmlstream, int len)
//如果是英文直接複製就可以

《UTF 8與GB2312之間的互換》的改進
在utf 8,與unicode之間轉換的時候，用二進位制運算，代替了字串的轉換。utf 8乙個漢字，用3個位元組，而unicode用2個位元組。對應關係如下 utf 8編碼 1,1,1,0,a5,a6,a7,a8 1,0,b3,b4,b5,b6,b7,b8 1,0,c3,c4,c5,c6,c7,c8...
在PHP中進行GB2312與UTF 8的互換。
因為證書中有中文，所以需要在php中進行gb2312與utf 8的互換。網上搜尋一下這方面相關資料，說是需要php iconv.dll的支援，可是我在php5資料夾中根本找不到這個檔案，但是奇怪的是在php4中有這個，然後我將php4中的php iconv.dll檔案，複製到system32下，卻提...
