Question

如何更改unicode

Answer 1

可以使用windows的函数MultiByteToWideChar,WideCharToMultiByte做相互转换.
下面是关于这两个函数的说明.

如果使用delphi编个程序转换,可以使用StringToWideChar和WideCharToString两个函数实现.

The MultiByteToWideChar function maps a character string to a wide-character (Unicode) string. The character string mapped by this function is not necessarily from a multibyte character set.

int MultiByteToWideChar(

UINT CodePage, // code page
DWORD dwFlags, // character-type options
LPCSTR lpMultiByteStr, // address of string to map
int cchMultiByte, // number of characters in string
LPWSTR lpWideCharStr, // address of wide-character buffer
int cchWideChar // size of buffer
);

The WideCharToMultiByte function maps a wide-character string to a new character string. The new character string is not necessarily from a multibyte character set.

int WideCharToMultiByte(

UINT CodePage, // code page
DWORD dwFlags, // performance and mapping flags
LPCWSTR lpWideCharStr, // address of wide-character string
int cchWideChar, // number of characters in string
LPSTR lpMultiByteStr, // address of buffer for new string
int cchMultiByte, // size of buffer
LPCSTR lpDefaultChar, // address of default for unmappable characters
LPBOOL lpUsedDefaultChar // address of flag set when default char. used
);
