I exported a list of characters say:
ClearAll[t, r, \[Theta], \[Phi]]; Export["hello.txt", {t, r, \[Theta], \[Phi]}, "List"]; the file has the correct symbols when opened with a text editor, however, when I imported it with Mathematica:
old = Import["hello.txt", "List"] I get:
{t, r, θ, Ï} Any idea of how can I recover the original symbols?
