ASCII - HTML - Unicode Character Entities Chart #000-3199

To bring up ASCII characters you do not find on your keyboard, i.e., Þ and ©, you need an ASCII character chart.
Once you know the character's number, you hold down your ALT key and type the character number on your keyboard number pad, and release ALT. The character should appear in your document. However, some software programs will not take ALT as meaning you want to create a foreign character and might trigger some other function in the software. Be aware of this, it can cause you to lose your documents. You might consider creating the character directly in an dud email and copy / pasting --or, copying directly from a handy character chart like the one below, directly into your html document.
Some characters differ on keypad/ALT vs. HTML. For instance, ALT+225 on number pad=ß while HTML numeric value is 223 for ß. It is beneficial to memorize characters you may use often. Another example is Ñ, while in ASCII it is ALT+165 on the number pad, in HTML the equivalent is 209. However, in the case of the capital letter A, both A and ALT+65 on number pad, come out to the same character.
