[petrkr]

Add degree symbol to charmap, so we can use this library to show temperature.

Seems useful .. I will create a PR at the weekend unless @petrkr fancies doing that?

it's ok, I do not see point on doing whole repo clone just to add 1 line in 1 file. Just add it due normal coding.

Luckily we have tests that pointed out this doesn't work on Python 2.7. Not as simple as adding 1 line in 1 file unfortunately.. What version of Python were you using @petrkr?

[petrkr]

That laptop where I tested it got stolen. But everything I do on Python 3.x. Python 2 is already obsolete, does not make sense to use it or even do new things above it.

Sorry to hear that!

PSF still supports it, and so do we.

Then you can use probably some \codex version of degree symbol, as Python 2 is NOT utf-8 and only ASCII based, there could be that problem. But I do not use it for many years, so do not remember already.
