I have ÷ in .txt file in my android. When this division symbol is shown on android device, I see "�"
To make it worse, my laptop doesn't have division sign on keyboard. I used the above sign from wikipedia.
Any guess how can I resolve this.
You should use the Unicode value for any symbols such as the division symbol you have here.
Try the Unicode U00F7.
When using it within a String format like "\u00F7"
.
