I use JMP to do Linguistic analysis, for which I need to use symbols of the IPA (International phonetic association) (e.g. ingma, bared i etc.) as variables in my stats. When I import data into JMP, some of these symbols do not display in the table or the graphs I make. All I see are square boxes. However, in the table, you actually see the symbol when you click on the box. I try paying with the font settings but it doesn't solve it. Is there any way to fix this and get the symbols to appear in the graphs?
Another possibility is an encoding problem. For instance, JMP is assuming UTF-8 but the text file is using something else. You might try opening the file in a text editor like Notepad and resaving it as something distinct like UTF-16.
