Using Unicode in source files and missing Unicode characters

Question

Since I found out that clang was able to compile C ++ source files written in Unicode, I began to use it heavily when writing math code. Compare

uₙ₊₁ᵖ = A*uₙ + B*uₙ₋₁;
uₙ₊₁ᶜ = π * Aₜₒₜ;
uₙ₊₁ = uₙ₊₁ᵖ + uₙ₊₁ᶜ;

and

u_n1_p = A*u_n + B*u_n_1;
u_n1_c = pi * A_tot;
u_n1 = u_n1_p + u_n1_c;

For me it's like day and night: I understand the first part of the code, just reading it, while I just do not want to read the other.

I know that Python3 and Ruby allow Unicode source files, so this feature seems to be spreading.

Objections can be made against this kind of practice: for example, not all fonts support these characters, your source file depends on the encoding you use, and you must actually copy / paste (for example) the Unicode character somewhere in a text editor. However, I think the readability coefficient is really great.
