model 'è·³ã?­ã??ã??ã?¼ã?«'
  parameter Real e = 0.7 "å??ç?ºä¿?æ?°";
  parameter Real g = 9.81 "é??å??å? é??度";
  Real 'é«?ã??'(start = 1) "ã??ã?¼ã?«ã?®é«?ã??";

equation

If you copy-paste the first model into OMEdit, all non-ASCII characters turn into ????:

model '??????'
  parameter Real e = 0.7 "????";
  parameter Real g = 9.81 "?????";
  Real '??'(start = 1) "??????";
  Real '??' "??????";
  Boolean '??'(start = true) "true????????????????";
  Boolean '??';
  Real '?????';
  discrete Integer '??????'(start = 0);

equation 
  '??' = '??' <= 0.0;
  der('??') = if '??' then -g else 0;
  der('??') = '??';
  when {'??' <= 0.0 and '??' <= 0.0,'??'} then
      '?????' = if edge('??') then -e * pre('??') else 0;
    '??' = '?????' > 0;
    reinit('??', '?????');
    '??????' = pre('??????') + 1;
  
  end when;
end '??????';
