Unicode in Android

Question

i have a little problem by printing the complement symbol in android.

 char c = '\u2216'; 
 // should be the unicode for complement
 textView2.setText(c); 
 // gives out "" nothing
 // if i take
 c = '\u2229'
 // it works

But why i cant print out the complement symbol, where is the mistake ? if someone has a solution, it would be very nice to shar it. Thanks !

Answer 1

I think its a font issue .. the font used by Android studio supports that character while the android device (propably Robot font family) doesn't include that glyph.. solution would be to use proper font.

Here is the list of fonts support that character (U+2216): http://www.fileformat.info/info/unicode/char/2216/fontsupport.htm
