海子 今夜我不关心人类:unicode如何转换成ANSI?
来源:百度文库 编辑:神马品牌网 时间:2024/04/29 21:43:43
记事本保存的时候提示保存成ANSI时会使里面原有的UNICODE字符消失,若保存成UNICODE的话放在MP3里无法辩识..如何解决?
将unicode编码的文章打开,单击工具栏的【文件】,选择【另存为】,在页面最下方的【编码】栏设置即可
Win32 提供 MultiByteToWideChar 和 WideCharToMultiByte 将为 Unicode 的 ANSI 字符串和 Unicode 字符串转换为 ANSI。代码如下:
/*
* AnsiToUnicode converts the ANSI string pszA to a Unicode string
* and returns the Unicode string through ppszW. Space for the
* the converted string is allocated by AnsiToUnicode.
*/
HRESULT __fastcall AnsiToUnicode(LPCSTR pszA, LPOLESTR* ppszW)
{
ULONG cCharacters;
DWORD dwError;
// If input is null then just return the same.
if (NULL == pszA)
{
*ppszW = NULL;
return NOERROR;
}
// Determine number of wide characters to be allocated for the
// Unicode string.
cCharacters = strlen(pszA)+1;
// Use of the OLE allocator is required if the resultant Unicode
// string will be passed to another COM component and if that
// component will free it. Otherwise you can use your own allocator.
*ppszW = (LPOLESTR) CoTaskMemAlloc(cCharacters*2);
if (NULL == *ppszW)
return E_OUTOFMEMORY;
// Covert to Unicode.
if (0 == MultiByteToWideChar(CP_ACP, 0, pszA, cCharacters,
*ppszW, cCharacters))
{
dwError = GetLastError();
CoTaskMemFree(*ppszW);
*ppszW = NULL;
return HRESULT_FROM_WIN32(dwError);
}
return NOERROR;
/*
* UnicodeToAnsi converts the Unicode string pszW to an ANSI string
* and returns the ANSI string through ppszA. Space for the
* the converted string is allocated by UnicodeToAnsi.
*/
HRESULT __fastcall UnicodeToAnsi(LPCOLESTR pszW, LPSTR* ppszA)
{
ULONG cbAnsi, cCharacters;
DWORD dwError;
// If input is null then just return the same.
if (pszW == NULL)
{
*ppszA = NULL;
return NOERROR;
}
cCharacters = wcslen(pszW)+1;
// Determine number of bytes to be allocated for ANSI string. An
// ANSI string can have at most 2 bytes per character (for Double
// Byte Character Strings.)
cbAnsi = cCharacters*2;
// Use of the OLE allocator is not required because the resultant
// ANSI string will never be passed to another COM component. You
// can use your own allocator.
*ppszA = (LPSTR) CoTaskMemAlloc(cbAnsi);
if (NULL == *ppszA)
return E_OUTOFMEMORY;
// Convert to ANSI.
if (0 == WideCharToMultiByte(CP_ACP, 0, pszW, cCharacters, *ppszA,
cbAnsi, NULL, NULL))
{
dwError = GetLastError();
CoTaskMemFree(*ppszA);
*ppszA = NULL;
return HRESULT_FROM_WIN32(dwError);
}
return NOERROR;
}
你可以先在WORD中转换为unicode编码,然后在复制到记事本里。
