I have an MFC application where the Character Set is “Not Set”. What are the risks associated with running this application on a OS that has a Multi Byte Character Set code page?

The “Character Set: Not Set” option defines neither
_MBCSnor_UNICODE. That means that you’re using the *A series of functions. Those will return MBCS strings, even when_MBCSis not defined.If
_MBCSdoesn’t affect the strings returned from the *A functions, then what does it do? It maps some<tchar.h>tcs*functions to theirmbs*versions, instead of thestr*orwcs*variants. E.g. without_MBCS,_tcsrevmaps tostrrev, not_mbsrev.Therefore, you may not be able to reverse the multi-byte strings you receive from the OS, or edit them otherwise.
