I solved the problem by installing extra fonts; I cannot remember exactly which fonts I installed but from memory (and synaptic ;-)) I installed the following packages (the first being the most important one I think): ttf-bitstream-vera ttf-arabeyes ttf-junicode ttf-kacst
ttf-dejavu has plenty of accented Latin characters (e.g. those used in Czech) that ttf-bitstream-vera omits and is very similar to ttf-bitstream-vera in appearance.
