If you have any need for special characters, such as characters with accent marks, upside down question marks, "picture" characters (Japanese, Chinese, Arabic, Russian, Polish, etc.), a unicode font will be required. In Grapher, fonts are divided into the non-Unicode section (the first 255 characters of any font) and the Unicode section (any characters above #255).
The easiest way to add Unicode text is to select characters in the Windows Character Map and copy/paste into Grapher. You can also use the ALT + #### option. Hold down the ALT button and type the character number to use this method. There is also a Windows language toolbar that will allow you to type in another language. Any of these methods can be used to type text in a foreign language that requires unicode characters.
