Problem with non-unicode chars in ajax-like part

[kosmidis]

Hello to everyone... Can someone help me?
I installed sugarcrm in a windows sbs with apache 2, php 4 and mysql 4

I changed iso encoding to iso-8859-7 on every file needed and have no problem with greek storing it on the database or retrieving it...
Problem comes from the "Select" buttons or from the "ajax-like" menu

Example:
Let's say you save an account with a greek account name "τεστ account". This is done great so far...
Then go to "Contacts" create a new one and try to fill in account name. It cannot be found if i press "τ" cause it sees greek chars as garbage characters. If I press "Select" I see the account name correctly. When I click on the account name hoping to pass infos back to the "Contacts" page it pass it again with garbage chars (like Áíôþíç Ìßããá).

Any ideas?
I search in all files for iso-8859-1 and replaced it with iso-8859-7. i even set "SET NAMES GREEK" after mysql_connect.
Maybe a file(s) needs to be saved with different encoding(converted as utf8 or something)?

Thank you very much

After a little search i found that "includes/JSON.php" does a conversion that completely ruins the greek part of string...
See my solution but i could use a better one... You will see why

I found that if change line 131 from

 $ascii .= sprintf('\u%04s',bin2hex($char)); 
  

to

 $ascii .=  $char; //sprintf('\u%04s',bin2hex($char)); 
  

it works fine, but what happens with future updates?

Bigger part of script

 if ($this->multibyte == false) {
   if (ord($var{$c}) <= 0xFF) {
      $char = pack('C*', ord($var{$c}));
      $ascii .=  $char; //sprintf('\u%04s',bin2hex($char));
   } else {
      $ascii .= $var{$c};                                    
   }                            
} else {...
