Saves the character to the given file.
HRESULT SaveCharacter( OLECHAR* path, long filter, ICharacter* pchar );
A filter is specified to overcome potential ambiguity when more than one exporter exists for the same file extension or when multiple file formats share the same file extension. The filter index should match that used by OPENFILENAME::nFilterIndex when using the list of filters obtained by calling IEditCharacter::GetExportFilterList. NOTE: This will overwrite the given file if it exists without prompting the user.
