Minimal PHP Code Causing Issue

rector --dry-run in terminal of VS Code:

protected function isGzipped(string $content): bool
     {
-        return mb_strpos($content, "\x1f" . "\x8b" . "\x08") === 0; // phpcs:ignore Generic.Strings.UnnecessaryStringConcat.Found
+        return mb_strpos($content, ') === 0; // phpcs:ignore Generic.Strings.UnnecessaryStringConcat.Found
     }

It is not entirely clear whether the Rector breaks the code, or whether these are output features in the terminal. The changes look unusable, so no action has been taken.

Expected Behaviour

Multibyte characters must remain unchanged in the code and for display in the terminal.
