From what I’ve been told, that’s nothing compared to menopause! :eek:
Honestly, between periods, childbirth and menopause, I give two huge thumbs up ALL women, THE stronger sex in my mind! 
(wide tangent…)
Of course, what you actually see is “in your browser”, rather than “in Windows”. “In Windows” (depending where in Windows you are) you may actually get something different (like the box drawing character).
The common browser encodings are ISO-8859-1, MacRoman, and UTF-8.
You are then, in theory, at the mercy of whatever font is used, but since there is an agreed meaning for the first 256 characters in UTF-8/ISO-8859/Latin-1, any standard 256-bit font will display something that matches the agreed meaning (degree and Masculine Ordinal Indicator)
The modern internet default encoding is UTF-8.
Testing: 100° in the shade.
What I do for a lot of special symbols is type it’s name into Google* and copy-paste what comes up. The first hit I got was for something called degreesymbol.net which conveniently has the symbol in the title.
- Google has done Something Bad with it’s search results for my browser. Let’s see, set User Agent to another browser … okay, got pulldown menus. Partially fixed.
The thing with spacesuits is that with all the seals and bearings they have to allow egress and free rotation, they are not really all that air-tight. Also, the life-support systems are only designed to last about 8 or so hours. Between the two, I’d expect the suit to leak down to the ambient vacuum and the power to run out within a couple of days at the most, at which point the body wouldn’t have much more protection than if it were left outside (the suit would still reflect some solar radiation, though) and probably still desiccate like a desert mummy.
Missed the edit window, but here’s a link that mentions the suits on the ISS are allowed to leak up to 100ml per minute.
