This is something that has always concerned me about the “UTF-8 is always best” mentality, text from the languages of the vast majority of the world’s population generally takes up 50% to 200% more space encoded with `UTF-8` compared to their older national character sets (compared to `UTF-16`, which is the same size or only 100% larger, not 200%).
