SOLVED Probrem with greek letters

kostasp

Hi there,

I use 'datatable' to show data in greek but I can't see the greek charachers. What I see is rhombus. All the titles are shown right (in greek) like "oPaginate sFirst", "sInfo". Only the data from the server through JSON are wrong. To exclude database problems, I wrote a simple server:

[code]
$test ='{"sEcho":1,
"iTotalRecords":"3",
"iTotalDisplayRecords":"3",
"aaData":[
["1","10/10/2001","111ΔΕΗ","ποτό μπαράκι","12.40"],
["2","10/10/2001","Ενοίκιο","ταβέρνα","5.76"],
["3","10/10/2001","Διασκέδαση","τιποτα","8.90"]
]
}';
echo $test;
[/code]

This is the code in the client
[code]
$(document).ready(function() {
oTable = $('#example').dataTable({
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "index.php?m=public&a=datatableserver&onlymain=true",
"bPaginate": true,
"bLengthChange": true,
"bFilter": true,
"bSort": true,
"bInfo": true,
"bAutoWidth": true,
"aaSorting": [[ 1, "desc" ]],
"bStateSave": true,
iCookieDuration : 60*60*24, /* 1 day */
"sPaginationType": "full_numbers",
"oLanguage": {
"oPaginate" :{
"sFirst" : "Πρώτη",
"sLast" : "Τελευτ.",
"sNext" : "Επόμ.",
"sPrevious" : "Προηγ."
},
"sEmpltyTable" : "Δεν υπάρχουν εγγαφές για εμφάνιση",
"sInfo": "Εμφανίζονται η _START_η μέχρι _END_η εγγραφή από σύνολο _TOTAL_",
"sLengthMenu": "Εμφάνισε _MENU_ εγγραφές ανά σελίδα",
"sLoadingRecords" : "Παρακάλω περιμένετε...φόρτωση εγγραφών",
"sProcessing" : "Επεξεργασία...",
"sZeroRecords": "Δεν υπάρχουν εγγαφές για εμφάνιση"
},
"bJQueryUI": true
});
} );
[/code]

Am i forgetting something?

Just a guess, but probably format encoding error in your script that sends the json. try forcing your script (php?) to encode to utf-8 or whatever is compatible with greek chars.

maybe look into running your json though http://php.net/manual/en/function.utf8-encode.php
and maybe force header to Content-Type: text/html; charset=UTF-8 if it's not setting that

I forgot to say that i use mozilla and the plug-in 'firebug'. With the help of firebug,I can see that the XHR response is correct.

{"sEcho":1,"iTotalRecords":"3","iTotalDisplayRecords":"3","aaData":[["2","10\/10\/2011","Ενοίκιο","ταβέρνα","5.76"],["1","25\/12\/2009","ΔΕΗ","ποτά μπαράκι","120.40"],["3","01\/01\/2001","Διασκέδαση","τιποτα","8.90"]]}

So I think that php sends the data correctly. Something else is the problem

Also I used http://jsonlint.com/ (JSON validator) and the JSON string is correct

kostasp

if I add the php function utf8_encode() at JSON string:
[code]
$test ='{"sEcho":1,
"iTotalRecords":"3",
"iTotalDisplayRecords":"3",
"aaData":[
["1","15\/04\/2011","111ΔΕΗ","bar","12.40"],
["2","30\/11\/2001","Ενοίκιο","'.utf8_encode("ταβέρνα").'","5.76"],
["3","20\/10\/2010","Διασκέδαση","τιποτα","8.90"]
]
}';
echo $test;
[/code]

I get this as XHR response, in firebug

{"sEcho":1,
"iTotalRecords":"3",
"iTotalDisplayRecords":"3",
"aaData":[
["1","15\/04\/2011","111ΔΕΗ","bar","12.40"],
["2","30\/11\/2001","Ενοίκιο","ôáâΓ�Γ±Γ­Γ΅","5.76"],
["3","20\/10\/2010","Διασκέδαση","τιποτα","8.90"]
]
}

and in mozilla it's shown as : ôáâÝñíá

utf8_encode("ταβέρνα") -> "ôáâΓ�Γ±Γ­Γ΅"-> ôáâÝñíá

I found what was the problem. I use eclipse as editor and by default eclipse saves the .php files as ANSI code. I 've change that to 'utf-8' ( and I wrote all the greek characters again as they had changed to squares) and now all look nice
