there was a problem with the test environment client server on the 
same machine,  virtual hosting etc...

I tested this on a productive machines and as fare is i can see the   
json is working as expected.

thanks.

Only if your system locales don't support UTF-8. Install UTF-8 locales.

I can see clearly now what the patch of Jan is trying to do. :-)

The muche smarter way as i tried. Nomore back and forth conversions.
In theory this should fix the issue.

Unfortunately in the setCharsetEnvironment(){} function is another "bug".
(in NLS.php)

the NLS::setLang(); turns the charset back to iso,
before the utf-8 can take action.

Regards roman

I can confirm this solution (thanks to Roman too). It solves the 
described problem for me (had that problems with strings containing 
german 'umlauts') - i use JSON with python-simplejson (in ZOPE) 
externally. With XMLRPC i had not such charset problems.

good work ;)

Still no luck. Strings get cut off.  $response is still in ISO-8859-1
Will do a fresh install.  Hope that helps.

Please download a fresh copy of this file, revision 1.4.2.6. You might 
still have local modifications that interfere.

This does not change the charsetcoding of strings in $response.
@return string  The JSON encoded response from the server.

Still the same behavior for me.

Jsonrpc.php, which is delivered 2009-09-14: Horde Groupware 1.2.4:

Might be this one:
http://cvs.horde.org/h/chora/annotate.php/framework/RPC/RPC/Attic/jsonrpc.php?sa=1&rev=1.5

How about now?
There is no such line.

Works for me.

I let you know as soon as i know more...

Care to tell us how?

this breaks the json request.

Procedure during the a json call server side:

1. json is calling function &_kronolith_eventFromUID($uid) --> 
kronolith/lib/api.php line 1133
2. the event object get fetched:  $event = 
$GLOBALS['kronolith_driver']->getByUID($uid) --> kronolith/lib/api.php 
line 1137
-------------
    Get an event or events with the given UID value in   
kronolith/lib/Driver/sql.php,v 1.213 2008/10/18 04:20:42
    3. call function: &getByUID($uid, $calendars = null, $getAll = 
false) --> kronolith/lib/Driver/sql.php line 416
    4. the event get cached : 
$this->_cache[$this->_calendar][$event['event_id']] = &new 
Kronolith_Event_sql($this, $event) --> kronolith/lib/Driver/sql.php 
line 453
    5. call fromDriver(SQLEvent) in the class Kronolith_Event_sql 
method fromDriver($SQLEvent) kronolith/lib/Driver/sql.php line 871
    6. call $driver->convertFromDriver($SQLEvent['event_description'])

    7. Converts a value from the default charset to the driver's 
charset String::convertCharset($value, $this->_params['charset'])

       The String:: class provides static methods for charset and 
locale safe framework/Util/String.php,v 1.43.6.37 2009/03/30 15:31:38

       on top of this file the $GLOBALS['_HORDE_STRING_CHARSET'] =

This is way we get an iso-8859-1 formated event back from kronolith.

json does not like iso-8859-1.This leads us back on track:

call function getResponse($request) --> framework/RPC/RPC/jsonrpc.php line 47
return Horde_Serialize::serialize($response, Horde_Serialize::JSON) 
--> framework/RPC/RPC/jsonrpc.php line 88

       We have to make sure, that all strings in this responseheader are utf8.
       for this we should add the propper charset in   
Horde_Serialize::serialize($response, Horde_Serialize::JSON, 
"CHARSET") <---
       or make somehow sure, that we get all respondehaeder for json utf8.

What version of Kronolith is this? That line number has nothing to do 
with charset conversion, and furthermore, nowhere do we use 
$GLOBALS['_HORDE_STRING_CHARSET']. Are you sure this isn't a local 
modification?

In Horde 3.3.5 the response object from Kronolith is using wrong charset.

If Horde API is used to Power External Sites like this one:
http://theupstairsroom.com/67

Problem:
Strings get cut off

Reason:
kronolith/lib/Driver/sql.php (line 453)
Kronolith_Event_sql turns all utf8 strings into 
$GLOBALS['_HORDE_STRING_CHARSET'] = 'iso-8859-1';


Solution:

/lib/Horde/RPC/jsonrpc.php
class Horde_RPC_jsonrpc();
function getResponse($request);

Line 91
--   return Horde_Serialize::serialize($response, SERIALIZE_JSON);
++ return Horde_Serialize::serialize($response, SERIALIZE_JSON, 
$GLOBALS['_HORDE_STRING_CHARSET']);
