Implicit platform default charset

Reports method and constructor calls that implicitly use the platform default charset. Such calls can produce different results on systems that use a different default charset and may result in unexpected behaviour.


void foo(byte[] bytes) { String s = new String(bytes); }

You can use a quick-fix that specifies the explicit UTF-8 charset if the corresponding overloaded method is available. After the quick-fix is applied:

void foo(byte[] bytes) { String s = new String(bytes, StandardCharsets.UTF_8); }
