Search/Replace acts like it's always adding implicit +

[zb-z]

Probably the consequence of doing interactive highlighting and probably not visible till you have consecutive repeating strings. Turning on RegExp didn't help.

Additional problem - "Replace All" misses a number of matches. Don't have the time to chase "hows" and "whys" - there's probably some search string rewriting inside.

IdleX version: 1.18
sys.version: '3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)]'

Example (it's exhaustive - all combinations of 5 parenthesis. ):

stringsRW = [
'((((()))))',
'()(((())))',
'(()((())))',
'((()(())))',
'(((()())))',
'()((()()))',
'(()(()()))',
'((()()()))',
'()(()(()))',
'(()()(()))',
'()()((()))',
'(())((()))',
'((())(()))',
'(((())()))',
'()((())())',
'(()(())())',
'((()())())',
'()(()()())',
'(()()()())',
'()()(()())',
'(())(()())',
'((())()())',
'()(())(())',
'(()())(())',
'()()()(())',
'(())()(())',
'((()))(())',
'(((()))())',
'()((()))()',
'(()(()))()',
'((()()))()',
'()(()())()',
'(()()())()',
'()()(())()',
'(())(())()',
'((())())()',
'()(())()()',
'(()())()()',
'()()()()()',
'(())()()()',
'((()))()()',
'(((())))()',

Try: Replace ( with 1
Replace ) with 0

IdleX gives:

stringsRW = [
'10',
'1010',
'1010',
'10((0',
'10(0',
'1010(0',
'101010',
'10(010',
'101010',
'101010',
'101010',
'1010',
'1010',
'10(0',
'101010',
'101010',
'10(010',
'10101010',
'10101010',
'10101010',
'101010',
'101010',
'101010',
'101010',
'10101010',
'101010',
'101))',
'101))',
'10101)',
'10101)',
'10(01)',
'10101010',
'10101010',
'10101010',
'101010',
'101010',
'10101010',
'10101010',
'1010101010',
'10101010',
'101)10',
'101)',

and it should be:

stringsRW = [
'1111100000',
