@alinaghale88 @Zhuochengyu I came looking for an issue with iSlug as basically anything with a special character was passing for me. When using special characters, I noticed that the regex will only fail if the second character is a special character like in your first example. Any other position and it doesn't get caught. I think it has to do with the fact that the regex also requires the string to be at least 3 characters long. Once it's 3 characters long, special characters are not caught like your second example.
