Inspect them at the smallest and largest intended sizes, then under perspective if the game uses world-space labels. Compare filled glyphs before enabling outlines or shadows. Reserve atlas margins for the encoded range, filtering and requested effects so neighboring glyphs cannot leak into each other.\n\nThen test complete strings. Text shaping maps character sequences to suitable glyph forms and positions; it remains a separate requirement. HarfBuzz provides shaping for multiple writing systems.
