[question] Are non-ascii characters home-assistant best practice? about hass-blueair HOT 2 CLOSED

wow, I see what you mean from your screenshot. I don't use Prometheus but that doesn't look right. To be honest, I was looking for a constant that was pre-defined like the TEMP_CELSIUS and PERCENTAGE for those other air quality sensors and I came up empty handed so I just hard-coded them. TBH, I find the Home Assistant docs very difficult to use. I know, however, that Home Assistant has support for the unicode units by default because I saw them previously with built-in sensor data. For that matter, all temperatures have unicode... how does Prometheus handle °F or °C because the degree symbol is another unicode character.

It looks like the Prometheus exporter for HASS is smart enough to use the full word. I think I'll probably have to go look at how that built in unit intelligently uses the °C form in Lovelace, and "celsius" on export.
