  Yes, though the "occasion" will highly depend on the user locale. For someone this will likely never happen, for someone this will happen everyday.

  Yes, given that the font contains all required glyphs to represent the string "AHIygあ你말" is limited. That's also visible in my test 2. Previous tests were done in artificially high font size (32pt for example) and less dense texts so the original authors might overlooked this problem.
