"Have you ever tried to include a passage in a different alphabet in one of your documents, for example a quotation in Russian in an English document, only to find that you have no Cyrillic characters available? Or sent a Spanish document in electronic form to someone in Greece, only to be told that the accented Latin characters have been replaced by Greek characters? Or produced a Web page that includes technical symbols and found that it works with Windows but not with Mac OS or Unix?"
If you know the Unicode (hexadecimal) value of a character, you can use the ALT+X keyboard shortcut to enter the character directly in your document.
Type the Unicode (hexadecimal) value of the character. Press ALT+X. Note: The value string can also begin with U+.
Microsoft Word replaces the string to the left of the insertion point with the character you specified.
You can also use ALT+X to display the Unicode character code for a particular character. Place the insertion point to the right of the character, and then press ALT+X. The character is replaced by its character code. Press ALT+X again to switch back to the character.
