AI脚本选择相同重叠文本 以避免文本对象重叠的现象

/////////////////////////////////////////////////////////////////
//Select Replicated (Overlaping) Text Items v.1 -- CS,CS2
//>=--------------------------------------
// This script removes all duplicate overlaping text items from a document.
// The ONLY parameters it checks are top and left coordinates, and text contents.
// Anchor points within one point of each other are considered the same.
// (tolerance can be adjusted by changing the 'tolerance' value.)
//
// The lower duplicate objects are selected for manual removal.
