Chinese characters not printed correctly using printHTML on MacOS via QZ-Tray

This issue was originally discovered by a user on the qz-print googlegroups email chain

When printing a simple HTML snippet via QZ-Tray on Windows, all of the characters are printed correctly, but when printing this same HTML via QZ-Tray on MacOS, several characters are missing and there are extra blank spaces in the print result.

QZ Tray 2.1.2 / AdoptOpenJDK 11

The bug can be reproduced by printing a very small html snippet on Mac:

<p>3樓2</p>

There seem to be two workarounds:

  1. Separate ASCII and chinese characters using something like an additional span, e.g;
<p><span>3</span>樓<span>2</span></p>


--OR-- 2. Use { rasterize: true } when printing on Mac

The fact that it is not reproducible with { rasterize: true } suggests it's likely a bug with the JavaFX printing subsystem. I think we will need to file a bug report with our JavaFX provider to resolve this.
