Description
We should use the StandardCharsets.UTF_8 whenever possible.
Discussion
Note that there might be reasons where using StandardCharsets.UTF_8 is not applicable, e.g. if the API level of a module is set to Java 8 for compatibility reasons and the API accepting a CharSet is from a newer JDK.
Also there might be APIs which do not support the CharSet type.
In those cases we must keep the "UTF-8" charset usage.
Motivation
Consistency and efficiency.
