Review comment:
       The diapasons here are related to:
   - Latin block (characters from dead language and used in medicine, non English characters)
   - CJK with Latin (wrong and not fully covered)
   - variation of symbols (non characters) and some Arabic range
   
   Please referrer here for correct CJK ranges: 
    https://stackoverflow.com/questions/1366068/whats-the-complete-range-for-chinese-characters-in-unicode
   
   and you might include Japanese ranges as well
   
   To verify what is in the range, could be used (found with google) `https://qaz.wtf/u/show.cgi`. Mode `Hexadecimal range`, value for example : `\u00A0-\uD7FF` ->  `00A0-D7FF`
