Exception when registering Unicode Font

[dbschema-pro]

I got an exception registering an unicode.ttf font, FontFactory.register( LOCAL_FONT_FILE.getAbsolutePath(), "Unicode");

Do you have any idea which could be the reason? This happens only on one system, a MacOS with a Chinese locale. Eventually, I can add the unicode.ttf file.

What is the size of the font file? From the error, it sounds like the font file itself is corrupted.

The font is 16Mb large. Here is a link to it: https://dbschema.com/fonts/unifont.ttf The software also downloads it from the website. It is also possible that the download was broken.
