The behavior of defects and defect clusters near the melting region of a two-dimensional Yukawa system is considered in a wide range of the screening parameter kappa. The concentration of defects, their size distribution, and some other characteristics are found to be quasi- universal and independent of the kappa value. Simple indicators of melting are proposed for close-packed two-dimensional systems.
