Remarks

COM Signature

From textmgr.idl:

HRESULT IVsFormatFilterProvider::QueryInvalidEncoding(  
   [in]VSTFF format,  
   [out] BSTR * pbstrMessage  
);  

QueryInvalidEncoding allows the language service to supply an appropriate message when the user has chosen an encoding that is not supported by the language tools. For example, if the compiler is unable to accept Unicode or UTF-8 source files, it is appropriate to warn users that they have chosen an incompatible encoding.
