We show that the difference cross sections in unpolarized SIDIS e+N\to e+h+X and pp hadron production p+p\to h+X determine, uniquely and in any order in QCD, the two FFs: D_u^{h-\bar h} and D_d^{h-\bar h}, h=\pi^\pm, K^\pm. If both K^\pm and K_s^0 are measured, then e+e-\to K+X, e+N\to e+K+X and p+p\to K+X yield independent measurements of (D_u-D_d)^{K^+ +K^-}. In a combined fit to K^\pm and K^0_s production data from e+e- collisions, (D_u-D_d)^{K^++K^-} is obtained and compared to conventional parametrizations.
