I'm getting recurring errors from reportengine, looks like every time the hourly cron runs. I'm connected to a WMR88 with a RaspberryPi. Any ideas?

Perhaps you could say a little more about how you are set up, what has changed recently and so on. What has cron got to do with weewx?? Looks as though you have set ascii for gauge generator (not a standard part of weewx) rather than utf8 - so maybe you have a weewx.conf setting that is overriding the skins. Also see you are using the bootstrap skin - also not a part of standard weewx.

You have a Unicode character with code point 0xb0 (the degree sign), which cannot be converted to ASCII.

The solutions:

1. Find the character (the degree sign) and use something else;

2. appeal to the author of gauges.py to add an explicit conversion from Unicode to UTF8 (instead of to the default ASCII).

Thanks, that helped. I originally configured using Bootstrap on 3.3.1, and I was probably experiencing the 0xb0 error the whole time without noticing in the log file. After I removed the 0xb0 (degree symbols) from the Bootstrap/skin.conf I found that my config had some flaws in it so I redid from scratch for 3.4.0 and all seems to be working now. Somehow there are still some Angstrom characters in the gauges, even after fixing the skins, but at least I'm not getting loads of error messages.
