Android Question Character ◄ does not show on button

[jai]

I have four button with the following special characters- ▲ (Alt 30), ▼ (Alt 31), ► (Alt 16) and ◄ Alt 17).
The first 3 work fine but the ◄ does not. It won't show no matter how I code it, cut and paste or Alt 17.
Does anyone know why this peculiarity with this character and how can I can make it show?

I don't know why but... could you use this?

Button1.Text = Chr(8678) & " " & Chr(8679) & " " & Chr(8680) & " " & Chr(8681)

Thanks Luca. These codes generated all four directional arrows which is good to know. Would you happen to know what would be the similar code for left-pointing triangle (◄) which is the format I am using for the other arrows.

9668 but it is not visible!

  Button1.Text = Chr(9650) & " " & Chr(9658) & " " & Chr(9660) & " " & Chr(9668)

Does anyone know why Chr(9668) and Alt 17 (both representing the character ◄) remain invisible while other similar signs (▲ ▼ ►) show fine? How can this be made visible.

Luca, I found Chr(9664) to do the trick. It is a left pointing triangle but is about half the size of other signs. I will play with font size to adjust it temporarily until someone can help figure out how to make Chr(9668) or Alt 17 visible. Appreciate your help. Jai

I have same issue in my app, after a while (without solution), then I had to stop using it

Seems that Android default font is missing some characters, including the left pointing arrow. Maybe you can set the background image with a bitmap of the arrow instead.
