Polish language does not have similar accents, because it's simply another Slavic language in Europe region. Polish have like crossed characters, that Czech does not have. By contrast Polish does not have characters with caron, that Czech have. Sure several characters with acute or with diaeresis in use both languages, as well as many other languages around the world. And yes, i try to export fonts, as i wrote, with Texture Editor utility or with 3DSimEd, but in first case, utility crash with error and in second, 3DSimEd export it as DDS, but when i try to open DDS, an error ocurr as "Unknown Compression". Maybe it is because all these utilities read raw data from PSSG file and add own DDS headers, that in this case maybe are wrong and these DDS files are absolutely uneditable.
Now an idea occurred to me, that these fonts (DDS) is maybe editable via Adobe Photoshop as separate RGB layers (maybe i inarticulate it, but maybe you understand, what i mean), but i do not have this software for trying it. If you can, please try it and tell me if it work, please. Then i can try to get Photoshop for my work.
Yes, GRIDEditor will work with F1 2010 too, but for now i do not remember, where on internet i get it. I cannot violate copyright, then i don't know, if i can post/release it here without agreement of author or author of original post/release. I try find of author and ask him for release it here by him or by me. OK?
