用VS2005+DirectX9 SDK（手頭測試過的是2004年10月的DirectX SDK和2006年4月的DirectX SDK）編譯游戲會出現以下warning：
--------------------------------------------------------------------------------
d:\microsoft directx 9.0 sdk (october 2004)\include\d3d9types.h(1385) : warning C4819: The file contains a character that cannot be represented in the current code page (936). Save the file in Unicode format to prevent data loss
--------------------------------------------------------------------------------
要修正這個問題，不必要存為UTF8的文件，而是搜索_D3DDEVINFO_VCACHE，然后會看到：
typedef struct _D3DDEVINFO_VCACHE ...{
DWORD Pattern; /**//* bit pattern, return value must be FOUR_CC(慍? 慉? 慍? 慔? */
DWORD OptMethod; /**//* optimization method 0 means longest strips, 1 means vertex cache based */
DWORD CacheSize; /**//* cache size to optimize for (only required if type is 1) */
DWORD MagicNumber; /**//* used to determine when to restart strips (only required if type is 1)*/
} D3DDEVINFO_VCACHE, *LPD3DDEVINFO_VCACHE;
那四個亂碼的去掉就可以了
