Hi
How is it possible that when I look at the preview window, I see the Polish diacritics. When I open the details and look at an array of characters, I can see that this font does not supports diacritics for my country?

Sample:
http://www.dafont.com/kg-les-bouquinistes-de-paris.font?text=%26%23346%3B%26%23377%3B%26%23262%3B%26%23260%3B%26%23346%3B%26%23280%3B%26%23321%3B&l[]=10&l[]=1&l[]=6&back=theme

For the moment, there are no diacritics, cyrillic, greek,... in the character table of dafont.

Are you saying that dafont does not support them, but the font is the support?

It's just not provided to display that in the preview Window.

At the moment, the characters table does not show all the characters available in the font. It shows what is considered to be the most "used" characters, just to give an example in one blink. Of course, if you type your own text, with special characters, and if they are available in the font, they will show up in the custom preview field
