I want to use proxima nova font in InDesign, but I have a problem with special characters like ę, ł, ź. How can I enable it?
What problem are you having and are you sure that font contains those glyphs?
What do you mean? What happens when you try to type them? Proxima Nova is intalled in my computer and all these characters are available in the glyph panel (I have not a Polish keyboard).
