Typing special characters:
- In Windows, the simplest way to type special characters is with the Character Map, or
charmap.exe. Scroll through, double-click the ° symbol you need, click Copy, and you can Paste it into your application. Notice though - while it's selected, there are codes at the bottom. On the left is the Unicode code,
U+00B0. This means that the system stores the degree character as hex
B0. (Who cares? We'll come back to it.) On the right, you see
Alt-0176. This means that when NumLock is turned on, you can hold Alt and type
0176on the number pad and get a degree symbol.
- In Linux, we need that Unicode code. Press Ctrl-Shift-U, then type
00B0and hit enter or space or whatever. The ° appears!
If you need to type something you haven't found in charmap, you can Google it. The lobster emoji, for example, is apparently
1F99E. So, on my Linux system, I hit Ctrl-Shift-U, enter the code, and get
Want to type a lobster in Win 10? If you're up-to-date on patches, you can hold Win and press . or ; to get the emoji picker.
