Unicode and ascii handbook
A lot of people use altcodes or have to look up the symbol on the web...but what if I told you there was an easier way?
On Windows or Chrome OS, hit ctrl+shift+u
it should type a u, typically underlined(u)
Then, you type the code and hit space or enter. There are a few things to keep in mind.
A) Length: All Unicodes are 8 characters or less
B) Characters: Characters accepted are 0-9 and A-F. This is because it is hexadecimal.
C) Arrow keys do not function in the editor. If you mess up, you have to delete characters to fix it. If it says capitalize it, ignore it. it isn't case sensitive. The Shift keys don't work in the editor, either.
D) Leaving the tab will exit the text editor, leaving u followed by any text entered as plaintext. In addition, to exit the editor you can delete the u.
E) You can find the code by googling how to type...(insert character or name here) and using the hex entry. Conversely, you can use unicodelookup.com or a similar site and search for the character using text or the symbol.
F) Leading 0's: The code for pi(π) is listed as 03c0. If I leave off the leading 0 and type 3c0, I will still get π.
G) Certain characters, like ͡ or ͜ are placed above or below the following character, like this: ͡° or ͜ʖ
H) I will also list alt codes.
