Hi. I get the wrong formatting in my pie chart when I use special characters. In my script datasource I have tried with u “m³”, but it is displayed as Âm³. What can I do?

I see the `str()` function where you are generating rows. That reverses the effect of the u’’ syntax.

You can try using the `unicode()` builtin instead of `str()`, or simply avoid that type coercion for known types.

I have another problem with the Report - Bar Chart component. It can display special characters like “åäö”, but not m³…

Reporting isn’t scripting. It doesn’t use the u’’ prefixes at all, and I don’t think it needs them.

The source dataset comes from a script.

Ah, I see. That is probably a problem with the font. Not all fonts implement all characters.

I think reporting is mangling the data keys, in some misguided attempt at sanitization.

Unfortunately I’m not sure if there’s a good fix. You could probably apply correctly encoded names in `configureChart`, but how would you know the correct name(s) to reapply outside of hardcoding things?
