    Coderslang_Master I am having the same problem, what could be the issue? My code looks like this:

    export const hasUpperCaseLetters = (s) => /[A-Z]/.test(s)

        emily The problem with the regex is that you're only testing for English characters and don't consider other alphabets. Examples: ÛÁŸ.

        Find a way to solve this task without a regular expression.
