    So as I mentioned in JIRA I don't see a way to do it in checkstyle rule. 
    
    I managed to implement a test that performs the check using `Reflections` 
but I don't know where shall I place it. The problem is that only files from 
packages that are dependencies to the module with this test will be checked. 
First idea I had was to put it in the `filnk-tests` module, but it does not 
depend on e.g. any of `flink-connectors`

> In a couple of places we convert Strings to bytes and bytes back to Strings 
> without explicitly specifying an encoding. This can lead to problems when 
> client and server default encodings differ.
> The task of this JIRA is to go over the whole project and look for 
> conversions where we don't specify an encoding and fix it to specify UTF-8 
> explicitly.
> For starters, we can {{grep -R 'getBytes()' .}}, which already reveals many 
> problematic places.
