EM_SETCHARFORMAT documentation have been explained,
WParam
Character formatting that applies to the control. If this parameter is zero, the default character format is set.
Try SCF_SELECTION

A Microsoft Rich Edit 2.0 and later, This parameter can be a pointer to a CHARFORMAT2 structure, which is an extension of the CHARFORMAT structure. Before sending the EM_SETCHARFORMAT message, set the structure 's cbSize member to sizeof (CHARFORMAT) or sizeof (CHARFORMAT2) indicate which version of the structure is being 2.
The szFaceName and bCharSet members may be overruled The when invalid for characters, for example: Arial on kanji characters.
