1. Create new Unity project using Universal 3D Template
2. Import provided font Asset “QA_Font.ttf”

4. In the Inspector window, set Character to “Custom Set”
5. In Custom Chars > text container enter “A” and press Enter
6. Enter “B” and press Enter
7. Enter “C” and press Enter
8. Observe the text container with text entered
