[imp] json_encode errors

[Jie Gao]

Hi All

horde-webmail-1.2.2
-------------------

I am experiencing the following problems:

1. In the error log there are such error lines:

PHP Warning:  json_encode() [<a href='function.json-encode'>function.json-encode</a>]: Invalid UTF-8 sequence in argument in /usr/local/www-mail/horde/lib/Horde/Serialize.php on line 270

The user seems to be using a Chinese OS.


2.  In the error log there are such error lines:

File does not exist: /usr/local/www-mail/horde/imp/mswordAmqQ2l0.png, 

However, the app puts such files in /tmp. 


3.  In the error log there are such error lines:

- script '/usr/local/www-mail/horde/util/go.php' not found or unable to stat
- File does not exist: /usr/local/www-mail/horde/pagerror.gif
- File does not exist: /usr/local/www-mail/horde/imp/StrangeNoGraphicData
- File does not exist: /usr/local/www-mail/horde/pagerror.gif

Any help is appreciated.
