No, there is no flag set, and I think it doesn't help if it were
available – either you trust a font that it is valid, or you don't.
This said, you might access the 'cmap' table directly (using
`FT_Load_Sfnt_Table`) and check whether it contains a Unicode
sub-table. If it doesn't, FreeType's Unicode cmap is synthetic.
