I like go in add spaces between the value and the unit in documents other people have prepared, when they write 50°C or something. The standard says there should be a space: 50 °C
Non-breaking spaces, even better in my opinion 😘👌
(Alt+0,1,6,0 on the numpad for all my homies using Windows at work)
Don't get me started on people using O's with super script to get degrees, drives me nuts. (Alt+2,4,8, or find it in the MS Word symbols menu ffs)
