With QPDF v16.11 I'm using LoadFromCanvasDC() to save a PDF file, but Japanese and Chinese characters appear as blocks. I've tried
1. excluding embedded fonts with NoEmbedFontListAdd(). That removes the boxes, but nothing is rendered in their place.
2. explicitly loading "Noto*.ttf" fonts. No change.
3. calling AddCJKFont(). No change.

Any hints? Thanks.

Hi Sam,

what's your dev environment?
You have to deal with unicode strings - otherwise no success.
You're sample code was great for better advice.

Cheers and welcome here,
Ingo

Thanks for the quick reply.

We're using Visual Studio 2015. The strings come from UTF-16 resource files. In the code, all strings are wide. Does that count?

Where the strings come from doesn't matter.
It's important how to handle inside your app.
You can search hear through the threads (top, right, enhanced search option) or here:

BTW: I think utf8 should be better
