Regional indicator flags (2 cols)
Regional Indicator symbols are paired to form flag emoji. For example, 🇺🇸 (US flag) is the sequence U+1F1FA U+1F1F8. A terminal that handles these correctly renders the pair as a single 2-column wide flag glyph.
How this is tested: Write a regional indicator pair (e.g., U+1F1FA U+1F1F8 for US flag), verify it renders as a single 2-column glyph.
