Question

I\'m attempting to display some text in my program using (say) Windows GDI and some of the unicode characters are displayed as boxes? What is up?

Answer 1

I had this same box/character/text issue for about 2 years on Chrome for Win10 and tried all suggested fixes but none worked for me. My problem was caused by an app I hadn't considered. I use uBlock Origin to cut-down on pop-up ads. By default, uBlock also "blocks remote fonts on this site", actually every site. When the fonts are blocked then Chrome inserts something to take its place, usually a simple square or rectangle. If nothing else has worked, check you ad blocker. That function can easily be turned off and all correct text is then displayed.
