More support for unicode

This:
T(rn(99)).t(d=>d%2?'🐟':'🐠').a({[tr]:d=>ts(y-(ta(d/9)*y+(t*a(c(d/5)/20)))%w,s(d)*(y=h/2)+4*s(t/y))}).y({[f]:c2()})
looks a lot better than this:
T(rn(99)).t("<º)))><").a({[tr]:d=>ts(y-(ta(d/9)*y+(t*a(c(d/5)/20)))%w,s(d)*(y=h/2)+4*s(t/y))}).y({[f]:c2()})
If it works in the playground it should get picked up and work on the site.
