Add utf-8 character into string array

I need to assign a utf-8 character to string array. How could I do this? I was just simple pasting it into eclipse from wordpad but some characters are shown as rectangles for example:

equations[4][2] = "N=N₀2";

In this case it is subscript 0; This doesn't work (utf-8 code taken only as an example):

equations[4][2] = "N=N"+char(U+00BA)+"2";

Not all Unicode values are natively supported on Android. If you are trying to set a subscript or superscript to the text in a TextView or on a Button or some similar View with text, you can use HTML like this:

(TextView)findViewById(R.id.textView).setText(Html.fromHtml("X<sup>2</sup>"));

This is handy and easy for subscripts and superscripts. For other Unicode characters, if it doesn't display in Android, then it probably just means that it is not supported on the built-in fonts. In that case, you would need to import your own font.

Summary of Options: You can store the subscript 0 value in your array however you like, but once you need to display it in text on the device, you need to 1) Use HTML, OR 2) Import your own font.
