correctly. Then, somehow, repeat the build with the new TeXLive. This might
help experts catch and fix problems before users discover them.

Norbert asked who might do this. Perhaps we could find some documents on
ReadTheDocs that use lualatex to generate PDF. We could then go upstream to
the authors of the project.

By the way, the Python docs are available in Chinese PDF. Two
randomly chosen docs from the download there lists XeTeX 0.99998 as the

I've found a couple of Chinese language projects on RTD. However, neither

I don't have the insight and time right now to find more candidates on RTD.
