In Ignition 7.9, we’re able to render arrows from the unicode characters (0x2190 - 0x2200), and sometimes use those on labels as a clarification for the operators.
No matter what font is chosen in 7.9, it will always show arrows in the label. But I guess there’s some fallback fonts working here.
On 8.0 however we get those “character not found” boxes for most of the arrows.
Only Lucida Sans Unicode comes close (has a few unknown characters), and Cambria renders all glyps, but can’t be used as a default font due to being Serif.
Is there someone who can explain what fonts are used when, how fallback fonts are chosen and how it relates to the JRE/JDK (which I expect is the issue here).
And ultimately, how to change the configuration in order to have fallback fonts, and make the glyphs visible in the designer too.
