Superscripts and subscripts are not rendered correctly

**Describe the bug**
Trying to render select superscripts and subscripts results in a wrong rendering.

**To Reproduce**
Steps to reproduce the behavior including code snippet (if applies):

1. Render the following snippet:
```

U+00Bx (correct): x², x³, x¹


U+207x: x⁰, xⁱ, x⁴, x⁵, x⁶, x⁷, x⁸, x⁹, x⁺, x⁻, x⁼, x⁽, x⁾, xⁿ


U+208x: x₀, x₁, x₂, x₃, x₄, x₅, x₆, x₇, x₈, x₉, x₊, x₋, x₌, x₍, x₎


U+209x: xₐ, xₑ, xₒ, xₓ, xₔ, xₕ, xₖ, xₗ, xₘ, xₙ, xₚ, xₛ, xₜ

```
2. Notice that only the [U+00Bx chars](https://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts#Superscripts_and_subscripts_block) are rendered correctly.

**Expected behavior**
All the superscripts and subscripts are rendered correctly.
