The flag to indicate whether or not the source code has Unicode BOM.

The input source map passed from a compilation step before PostCSS (for example, from Sass compiler).
root.source.input.map.consumer().sources //=> ['a.sass']

set the from
option, or Input#id

root.source.input.origin(1, 1, 1, 4)
//=> { file: 'a.css', line: 3, column: 1, endLine: 3, endColumn: 4 }
