Unicode U+1F16A and U+1F16B do not render

[cooperate]

Describe the bug
Regardless of what font family I use, these glyphs do not render as expected and instead only spit out "<j" and "<k" respectively.

I noticed internally react-pdf has a fallback function for glyphs but something is wrong as the fallback does not render the glyphs as expected?

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

Attempt to render 🅪 and 🅫

Observe that regardless of font family, they only render <j and <k

Expected behavior
Render the glyph as expected.

We are having the same issues with other unicode character even if the font is correctly loaded and it has those symbols on it, for example

𝑥 𝐴 𝐵 𝑛

Using NotoSansMath

Hi romen I do have a solution for this to render unicode 16-bit characters but now I have issues with the font fallback pattern not working as expected..once I have this all resolved I will be making a PR.
