This may be a long post since I'm too lazy to build a fancy table. (For some of the characters below, you may also want to view in a larger than usual font size.)
The Alt-NumPad method of entering characters is "officially" limited to numbers between zero and 255. Some larger numbers work sometimes, but it's best to use Hex numbers, and the official Unicode character codes (which are in Hex in the Unicode tables). Several of the low numbers have no visible glyph associated, so there are some blanks.
For html posts, you can code a character by its DECIMAL number:
&#nnnn;
where the & announces the start of a code, the # says that the instruction is a number, the nnnn is the number, and the final ";" says that the code is done.
You can use the hex number in the same way, simply by adding an "x" to the code:
&#xnnnn;
where again the & announces the start of a code, the # says that the instruction is a number, the x says the number is in hexadecimal, nnnn is the hexadecimal number and the ";" closes the code.
In Word, you can type the hexadecimal number, and before spacing hit Alt-X and the character will (or should) magically appear.
For DECIMAL numbers 0001 through 0256, corresponding to HEXADECIMAL numbers from 0001 through 00FF:

For Windows, the Alt-NumPad method may give different results for some numbers, because when you select a language a different character map is used by the computer, and/or autoreplace functions may be invoked for your computer. Windows, and computers to use it with, are regionalized by where the computer is purchased so the differences depend on where you are and are NOT THE SAME for computers in different "language areas."
