In this case, the object
$selfis implemented as a blessed array reference rather than the far more common method of using a blessed hash reference. The syntax$foo->[42]accesses a single element from an array reference. Presumably,UTF8is a constant that returns a numeric index into the array.You see this idiom sometimes when people become convinced (usually incorrectly) that hash lookups on object attributes result in significant overhead and try to prematurely optimize their code.
