Convert Math in Text Form to $\LaTeX$ Form

Question

I have the following math as a text file:

text = {"aᵢ₁β₁ + aᵢ₂β₂ + ... + aₙ₁βₙ = bᵢ"}

Is it somehow possible to convert it clean $\LaTeX$ Input ?

The Goal: I want to convert it to clean $\LaTeX$ Input. So I thought, that converting it to Mathematica Input Form and then to $\LaTeX$ Input using TeXFormwould maybe do it. What do you think ?

Expected Result:

a_{i1} \beta_{1} + \a_{i2} \beta_{2} + ... + \a_{n1} \beta_{n} = b_{i}

$a_{i1} \beta_{1} + a_{i2} \beta_{2} + ... + a_{n1} \beta_{n} = b_{i}$

Answer 1

text = "aᵢ₁β₁ + aᵢ₂β₂ + ... + aₙ₁βₙ = bᵢ";
text2 = StringReplace[text, {"ᵢ" -> "i", "₁" -> "1", "₂" -> "2", "ₙ" -> "n"}];
TeXForm[ToExpression[StringReplace[text2, 
   {"..." -> "…", a : "a" | "β" | "b" ~~ b : "i" | "n"|DigitCharacter ~~
    c : (DigitCharacter ...) :> 
      StringJoin["Subscript[", a, ",", b, c, "]"]}], StandardForm, HoldForm]]

$a_{\text{i1}} \beta _1+a_{\text{i2}} \beta _2+\ldots +a_{\text{n1}} \beta _n=b_i$
