Gnus was usually stopped responding and lagging several seconds when
scrolling before the fontset customization. It is much better now.

I need to pair every fonts name and script name for every
script/language but I do not know the font name for some
scripts/languages. So I leave Emacs to find the correct font and use
M-x descript-char on these language's character to find the font name.
When there are many languages, it takes some time. And I also found I
made some mistake before, so I need to delete the incorrect one and
repeat these step for that specific script/language again.

This is my font setting, the Linux part is not complete, because
currently, I am on my Windows box.

As you can see, some fontset settings were taken from your previous
post. I only modified the font name to adjust my machine, other parts
is my own. I believe this setup covers all the characters range in the
HELLO file?
