font-language-override

The font-language-override CSS property controls the use of language-specific glyphs in a typeface.

By default, HTML’s lang attribute tells browsers to display glyphs designed specifically for that language. For example, a lot of fonts have a special character for the digraph fi that merge the dot on the “i” with the “f.” However, if the language is set to Turkish the typeface will likely know not to use the merged glyph; Turkish has two versions of the “i,” one with a dot (i) and one without (ı), and using the ligature would incorrectly transform a dotted “i” into a dotless “i.”

Syntax example: font-language-override: normal;
