They seem to be working after changing the devanagari font to Noto Sans
Kaithi but only for one digit though, also they do not appear when alone.
Since the kaithi unicode does not have its own numerals and uses the
devanagari ones, is there any way to only change the devanagari font when
it is near the kaithi number signs?

Here is the Text I entered, sorry for not including them earlier, I thought
that mentioning their codepoints should be enough.
KAITHI NUMBER SIGN: 𑂽
KAITHI NUMBER SIGN + DEVANAGARI 0: 𑂽१

KAITHI NUMBER SIGN ABOVE: 𑃍
KAITHI NUMBER SIGN ABOVE + DEVANAGARI 0: 𑃍०
