string manipulation - Convert ASCII Characters to Mathematica Input Form

I have the following pure ASCII character list:

list ={"a", "\\:1d62", "\\:2081", "\\[Beta]", "\\:2081", " ", "+", " ", \
"a", "\\:1d62", "\\:2082", "\\[Beta]", "\\:2082", " ", "+", " ", ".", \
".", ".", " ", "+", " ", "a", "\\:2099", "\\:2081", "\\[Beta]", \
"\\:2099", " ", "=", " ", "b", "\\:1d62"}

How can I convert it to Mathematica Input Form ?

I tried: FromCharacterCode[ToString[#, "ASCII"] &/@list

But it does not work.

As @Rohit suggests in the comments, one possibility is to use ToExpression. However, to be safer, one might want to use Symbol instead. So:

Replace[
    list,
    a_ /; StringLength[a] > 1 :> Check[SymbolName @ Symbol[a], $Failed],
    {1}
] //InputForm

{"a", "ᵢ", "₁", "β", "₁", " ", "+", " ", "a", "ᵢ", "₂", "β", "₂", " ", "+", " ", ".", ".", ".", " ", "+", " ", "a", "ₙ", "₁", "β", "ₙ", " ", "=", " ", "b", "ᵢ"}
