Are there any changes in RegEx implementation in Kotlin/JS 1.5.0? After upgrade from 1.4 to 1.5 I have an error like this Uncaught SyntaxError: raw bracket is not allowed in regular expression with unicode flag in kotlin.js:44848 probably with this code:

fun validateEmail(value: String): Boolean {
    return value.matches("^([a-zA-Z0-9\\-_.]+)@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}])|(([a-zA-Z\\-0-9]+\\.)+[a-zA-Z\\-0-9]{2,}))$".toRegex())
}

this is failing when 1.5.0 is selected, but works fine with 1.4.30

I think this is the issue: https://youtrack.jetbrains.com/issue/KT-46694

@Robert Jaros

Done some looking for you. While your example doesn't work, I've not faced an issue on my end as I was building my expressions using RegExp

I have 1.5.0 also and IR comp.

Here's an example that might be a workaround for you. https://pl.kotl.in/RQ8GZ-8Hx

I also has a look at your RegEx and it seems to be invalid. The link above has a regex that I use for Emails. Feel free to grab it!
