Safer password More secure with Characters UTF-8

Hello,
I wondering why stuck with English when the service targeting World Wide
I see there two scenario :

  • make possible to change password generator to another language
    Advantage:
    – easier to Remember
    Disadvantage:
    – there is websites not supported,so
    there could be main language as chosen by user and there secondary is English that can switch to it,easily
  • adding another option beside special charter for foreign languages
    Disadvantage:
    – very hard to Remember
    Advantage:
    – more secure than generator bcs target more than one language.
    Best Regards
