"Invalid Regular Expression"

[smilinger]

Hi, I type a RegEx in the search box and it says “Invalid Regular Expression”. My Regex is “(?).*(?=)”, which should be right. I have test it with some Regex Tester and it works.
I tested more and found emeditor did not support +/*/? in (?

That is true. The pattern in (?<=exp) must be fixed length.
