The gain can be an increase in readability. For instance, being able to use δx or ΔT as variables (e.g. in Julia) instead of delta_x, delta_T or similar. Mathematical expressions become more like the actual mathematics. Julia, in particular, actually uses unicode characters for some of the operations, such as for i ϵ 1:10 although you can still write for i in 1:10 if you need to. And you might be able to imagine being able to define operators such as · and × for vector arithmetic. Etc. US-ASCII is very limiting for expression.
