Comment (by karsten):

 Hmm, looks like the current code already contains such a run-time
 verification:

 {{{
     try {
       // ...
       BufferedReader br = new BufferedReader(new InputStreamReader(
           new FileInputStream(this.geoLite2CityBlocksIPv4CsvFile),
           "UTF-8"));
       // ...
     } catch (IOException e) {
       log.error("I/O exception while reading "
           + this.geoLite2CityBlocksIPv4CsvFile.getAbsolutePath() + ".");
       return lookupResults;
     }
 }}}

 The differences to your code are that the encoding is specified using a
 String and that CharacterCodingException is not caught directly but its
 super class IOException.  But I think the effect should be the same, no?
