FIX: Moved percent sign to right

[jamesshannon]

Hi. Thanks for all the work on this.

With that being said, the formatting of the percent sign was driving me crazy. :) In the US, at least, the percent sign goes after the number. I see you're from AU, and I thought it was the same?

Assuming that there are some locales where % comes before the number, that formatting should be handled by HA, but I couldn't find any useful l10n code.

You are correct, this is one thing most of the world can agree on. There appears to be some exceptions but I don't believe these are catered for in HA or most OS's for that matter. I share your pain every time I look at the m/d format on my fitbit.

The format on the adjustment attribute wasn't meant to be human readable. Just like dates which need to be localised the adjustment should also be formatted. The idea is the first character is the operator one of +-=% and then follows the value. This makes it simple with jinja code to do the crazy things people expect.

It would be best if the humanisation was done on the frontend along with language, date/time, numbers etc. At the moment the adjustment on the card just reflects the entity attribute, probably a little lazy. I can add some formatting to the card to ease the suffering. Doing this on the backend as you propose will break many tests that are in place.
