I debated where to post this, but since it is more of an opinion question than a factual question it should go in GD.
Many European (and other) languages use variants of the Latin alphabet, East Asian languages often do not. When I look at a label or set of instructions (especially from a European product) it can take a few seconds to find the English writing. I easily skip past the Korean, Chinese, Arabic, and Japanese, but when I am faced with 6 or seven paragraphs all written in the same font, it takes a bit of time to find the <GB> or Union flag used to indicate English.
Up until 80 years ago or so, many languages used their own variant fonts with the Latin script so we had the German Blackletter and the Gaelic Script, etc… I can imagine it would be so much easier on bilingual road signs & packaging to find exactly the language you want if each had its own characteristic font. In this age of computers where changing a font is just a point-and-click, isn’t this technique advocated? Do others agree or disagree that this would benefit consumers (as well as drivers in bilingual areas?)
The flags do the job pretty well, and having a mishmash of typefaces on packaging would be poor aesthetics. Companies spend a lot of time developing brand identity, and even down to the choice of font for things like ingredients or instructions have a lot to do with the image they want for the product. Plus there would be readability concerns with some of the faces you have in mind.
I think it would be good. Right now some packaging inserts do that. I’ve bought appliances and IKEA-type assembly furniture with different languages in different fonts, some bold, some italic, and so once you are reading in a specific font it’s easy to follow it from one illustration to the next.
But there are too many different languages in Europe alone to force each country to find its own.
The last country to choose, probably Norway, would only find the worst selection of choices remaining.
