thank you for destroying the CJK tables

The "all people" claim may be an exaggeration.

The module apparently picks the "Hans" script instead of "Hani". Maybe this is the issue?

They shouldn't use Hans. They are not specifically Simplified Chinese.

They are Hani now. Can you see them (after purging)?

Yep.

Then we seem to have a problem with Hans. Either get rid of it or fix the stylesheet.

Browsers are too smart. When they see Hans, they'll try to apply a Simplified Chinese font, even though the choice might not be the smartest.

But they do so because of our styles for .Hans. This is a regular CSS class, its assigned fonts can be changed. Question is, to what. And whether.

Eh, I just noticed I have a custom hack in my CSS, that works by specifiying Ext-B fonts first and then regular CJK fonts. I don't know why it works (must be black magic) but it does.
