This replaces a print statement with a logging statement for a warning that is emitted when no LANG etc. settings are present in a system.
Using stdout/regular print statements is not recommended for logging purposes as it is not possible to control the verbosity of the output. And I breaks tools that rely on the stdout to be clean or have a certain format.
In general terms, I'd recommend to use logging in all places where print
statements are not used as an API or CLI output.
