Hi, @coises and All, Sorry, but I came across a serious bug regarding the ICU search, since Search++ version v0.6 The Find in Selection, Find in Marked Text and Find in Whole Document options The Find All in Selection, Find All in Marked Text and Find All in Whole Document options Triggers the closure of Notepad++, without saving any configuration file and unsaved tabs After some quick tests : The Select, Mark and Show options, The Count in Selection, Count in Marked Text and Count in Whole Document Seems to wotk correctly in ICU mode BR guy038
