Hi Marija,
I think this is bug MDL-10823 which I reported a few weeks ago, but it has been fixed.

Muchas gracias, Eloy,

However, it only works with the first syntax. If I want to return the first 30 characters of string $mystring:

$return = $textlib->substr($mystring, 0, 30);

works ok

$return = moodle_substr($mystring, 0, 30);

does not work.

PS.- In the meantime I had used this small function, which works welll:

 function utf8_substr($str, $from, $len){

 return preg_replace('#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$from.'}'.

 '((?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$len.'}).*#s',

 '$1',$str);

 }

Tried to put this in my function:
global $CFG;
include_once("$CFG->dirroot/lib/typo3/class.t3lib_cs.php");
still no luck...

I need to use a substr function on non-latin character language. Of course, the php function substr() does not work correctly, so I need to use the utf8_substr() which exists in lib/typo3\class.t3lib_cs.php. But how do I "call" this function? Do I need to put a GLOBAL or INCLUDE in my php file so that it does not tell me "Call to undefined function utf8_substr()"?
Thanks in advance,
Joseph
