Per Unicode CLDR + game studio guidelines, FONT FALLBACK chains are necessary because of which constraint?
ABandwidth limits prevent loading any custom fonts
BNo single font contains glyphs for every supported script
CAll fonts must be uppercase-only on mobile platforms
DConsole TRC bans loading any font assets at runtime
Answer & Solution
Correct answer: B. No single font contains glyphs for every supported script
Unicode Standard + Noto fonts project + Unity/Unreal docs: a fallback chain (Latin → CJK → emoji → fallback) renders glyphs missing from the primary font. Critical for CJK + emoji + Indic scripts.
