android - Special characters in a TextView

Question

I want to show the "?" character in an Android TextView, but it shows [] instead.

This is my code:

txtCatname.setText("?");

How can I display this symbol correctly?

Answer 1

You can use an Unicode code: http://unicode-table.com/en/.

Such as:

txtCatname.setText("u266b");

or alternatively use an iconic font, such as font awesome:
http://fortawesome.github.io/Font-Awesome/

Use this alternative (or any other iconic font you like), in case this character isn't supported (not all Unicode characters are supported).
