Dug through that. The font referenced for unit_label_font_path in skin.conf for Seasons is "font/OpenSans-Bold.ttf", which does exist. Thinking it might not have full support for the Unicode math symbols, I changed that to "/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf", which supposedly covers all 256 symbols. And I still have the weird unit label...nothing there changed. I see no error messages WRT rendering in the log as described in the User's Guide.
What's quite odd is that the rendered text contains both the "micro" and the "cubed" symbols...it just has the extra garbage as well. And I found where this unit value gets defined: in /usr/share/weewx/unit.py: "microgram_per_meter_cubed": u"µg/m³". In the HTML for the "current" line, this looks reasonable: "µg/m³". But I have yet to make the image generator happy. --Richard On Monday, April 5, 2021 at 2:39:06 PM UTC-7 gjr80 wrote: > Hi, > > Nothing to do with drivers or extensions, it’s a font issue.
