'description' => isset($icon[1]) ? trim($icon[1]) : '',

# Notes:
#   • This currently omits the 12 keycap bases, the 5 modifier characters, and 26 singleton Regional Indicator characters
#   • The file is in CLDR order, not codepoint order. This is recommended (but not required!) for keyboard palettes.
#   • The groups and subgroups are purely illustrative. See the Emoji Order chart for more information.

# group: Smileys & People

# subgroup: face-positive

# Notes:
#   • This includes the emoji components that need emoji presentation (skin tone and hair)
#     when isolated, but omits the components that need not have an emoji
#     presentation when isolated.
#   • The RGI set is covered by the listed fully-qualified emoji. 
#   • The listed minimally-qualified and unqualified cover all cases where an
#     element of the RGI set is missing one or more emoji presentation selectors.
#   • The file is in CLDR order, not codepoint order. This is recommended (but not required!) for keyboard palettes.
#   • The groups and subgroups are illustrative. See the Emoji Order chart for more information.
