The kiwix icon on Ubuntu 20.04 installed with the ppa have a bad resolution.

More and more people use kiwix-serve on ARM based GNU/Linux and more and more people uses Docker on ARM based GNU/Linux. This is why I believe, this might be helpful. Seems doable and relatively easy by following this example:
https://hub.docker.com/r/ckulka/multi-arch-example

This would help to reduce energy consumption:
https://web.dev/native-lazy-loading/

This shoudl be trivial to implement.

Remark: no implementation so far at Mediawiki level, see https://phabricator.wikimedia.org/T230812

Latest QUnit is 2.22.2 from 09/09/2020.

(Maintaining dependencies would be much easier if we could start #554...)

This class is nice. I may worth to move this in libzim's tools and use it everywhere we create a stringstream in our code.
This could even be merged with a to_string function.
