코딩시 Unicode 관련 고려사항

윈도에서 코딩시
유니코드 적용해야 할때
#Define _UNICOE 을 하면
기존에 잘 컴파일 되던 플젝이 에러 투성이로 변하는 경우가 발생하져..ㅜㅜ

이런경우 당황하지 하지 마시고 모든 에러요인을 찾아다니면서 삽질을 하셔야 할껍니다.

아래와 같이 하시면 대략의 삽질은 면하지 않을까요..?? ^^
( 물론 직접 소스를 찾아가 수정을 가해야하는 부분이 발생하지만 아래와 같이 하시면 많은 부분의 수정요인이 사라지리라 생각합니다. )

1. 윈도 API를 사용한다.
sprintf 등 보다는 wsprintf등 과 같은 윈도에서 제공하는 함수나 MFC를 사용한다.
아무래도 UNICODE 설정만으로 한번에 변경하기 위해선 윈도에서 제공하는것을 써야할듯 싶습니다..^^

2. char * aa = NULL; 와 같은 char 사용시 TCHAR 을 사용한다.
ex> TCHAR *aa = NULL;

3. aa = "나텍스트"; 와 같이 텍스트 값을 사용할때는 _T("") 매크로를 사용한다.
ex> TCHAR aa[50] = { 0 , } , *a1 = NULL;
a1 = _T("나텍스트");
wsprintf( aa , _T("%s") , a1 );

3. 메모리 함수 memset , memcpy 등을 사용시 사용되는 스트링의 크기 ( 글자수가 아닌 ) 는 항상 ( sizeof(TCHAR) * ( 글자수 ) ) 로 한다.
ex> TCHAR aa[100];
memset( (BYTE*)aa , 0x00 , ( sizeof(TCHAR) * (100 ) ) );

4. 스트링 펑션을 쓸때는 _tcs... 으로 나가는 매크로를 사용한다.
ex> TCHAR *aa = "나도텍스트" , a1[50] , a2[50];
memset( (BYTE*)a1 , 0x00 , ( sizeof(TCHAR) * 50 ) );
memset( (BYTE*)a2 , 0x00 , ( sizeof(TCHAR) * 50 ) );

if ( 49 >=  _tcslen( aa ) )
{
_tcscpy( a1 , aa );
memcpy( (BYTE*)a2 , (BYTE*)aa , ( sizeof(TCHAR) * _tcslen(aa) ) );
}
