How to update fonts

[Alain D D Williams <addw@phcomp.co.uk>]

I am running Debian 12 - Bookworm.

I occasionally see Unicode characters that do not do not display properly. Eg:
메리 크리스마스 (for the curious: this says Happy Christmas in Korean).

These do however display properly on my laptop which runs Mint 21.3.

I suspect that I could see them if I used the testing version of some package.
Which one(s) and how do I do this ?

They fail to display in either Mate terminal 1.26 or in Firefox 128.5 so I
suspect it is a system thing.

Thanks in advance.
