// LABELS

// ---------------------------------------------------------------------
// Languages

// There are 5 language options in the MapBox Streets vector tiles:
// - Local/default: '[name]'
// - English: '[name_en]'
// - French: '[name_fr]'
// - Spanish: '[name_es]'
// - German: '[name_de]'
@name: '[name_en]';  
@name_local: '[name]';


// ---------------------------------------------------------------------
// Fonts

// All fontsets should have a good fallback that covers as many glyphs
// as possible. 'Arial Unicode MS Regular' and 'Arial Unicode MS Bold' 
//are recommended as final fallbacks if you have them available. 
//They support all the characters used in the MapBox Streets vector tiles.
