Summarize the following:
Click the Windows logo in the bottom-left corner of the screen. Type in character map to do so. It should be at the top of the Start menu. Doing so opens the Character Map window. Click the "Font" drop-down menu at the top of the Character Map window, then click a commonly used font (e.g., Arial) in the drop-down menu. The reason you need to do this is that less commonly used fonts include different symbols which aren't compatible with some programs. Scroll through the list of symbols until you find the one you want to use. Click once the symbol to select it. You should see the symbol enlarge slightly. It's at the bottom of the window. The symbol will be added to the "Characters to copy" text field. You'll find this in the lower-right corner of the window. Doing so copies the symbol to your clipboard. Once you've copied your symbol, open a text field or document, then press Ctrl+V to paste in the symbol.

Summary:
Open Start . Search for Character Map. Click Character Map. Select a common font. Find the symbol you want to type. Select the symbol. Click Select. Click Copy. Paste the symbol into a document.
