Might we run out of Unicode code points, like we (seem to) be running out of IPv4 addresses? As another comment mentions, once you add all these snowmen, with/without snow, male female and gender-neutral, in a few skin colour options (plus neutral)... it adds up. Plus, exponential growth once you consider family of snowmen (different number/genders/races of "parents", different number/gender/races of "children" and s…
1) there's only ~150k unicode values defined. If we assume a signed int for available space, we have 2,147,333,647 of 2,147,483,647 remaining. moreso if the int is unsigned. We're fine. 2) they use values that combine like ligatures to create the variants of values. there isn't a combinatorial explosion because color is a modifier value, and sex, and then the underlying symbol. It's not a unique symbol for each combi…
