Such classes will unfortunately have to be renamed. However, this is =
only true if the code needs to run on PHP 7. For PHP 5 codebase =
compatibility, Drupal can do this:

    class StringHelper {
        =E2=80=A6
    }
    if (version_compare(phpversion(), =E2=80=9C7.0") < 0) {
        class_alias(=E2=80=9CDrupal\\Component\\Utility\\StringHelper=E2=80=
=9D, =E2=80=9CDrupal\\Component\\Utility\\String=E2=80=9D);
    }

This way, only code made =E2=80=9CPHP 7-ready" will have to replace its =
references to String with, say, StringHelper. Drupal can work on both =
PHP 5 and PHP 7, but codebases using it can migrate at their own pace.
