I had similar problems using the Norwegian letter "Ø" as the first letter in the
elements it was simply not there after the fgetcsv transfer. The following
WORKAROUND worked for me using explode().

//read the text file into a variable
$txt=read_txtfile("test.txt");

//explode the stream into an array of $nr rows					
$rowArr = explode("\n", $txt);					
$nr=count($rowArr);

For ($r=0;$r<$nr;$r++){	
  
     $insert_data="'".str_replace(";",
"','",$rowArr[$r])."'";

     //insert each row in the DB table "test"
        $query_string=" INSERT INTO test (name,name2)"
         		." VALUES (".$insert_data.")"; 				$result_id =
mysql_query($query_string, $my_conn)
                        or die("display_db_query:" . mysql_error()); 
    }

    If ($result_id ==1){echo $nr." rows transfered<br />\n"; }
    

Function read_txtfile($infile){
// read text data from file into a variable
$txt='';
$fo=fopen($infile,"r");
$txt=fread($fo,filesize($infile)); 
fclose($fo);
return $txt;
}	

===================================================================
If there is a need to access each data column in the row before transferring, these can easily be
accessed by exploding each row once more in an inner loop.

In the window-versions it works correct,
I got the error under php 5.2.6-1+lenny13

Description:
------------
fgetcsv() throws away the first character of a field if it is invalid in the current locale, but
ignores invalid characters which are not at the beginning of a field. The inconsistent behavior
makes it hard to locate the source of the bug; it should either throw all invalid characters away,
or none of them (IMO the second is much better).


(This is a duplicate of bug 45356, but that one has been closed as "no feedback", and
apparently mere mortals are not allowed to reopen it, even if they do provide the feedback...)

Test script:
---------------
<?php

setlocale(LC_ALL,'C');
$utfchar = chr(0xC3).chr(0x89); // U+009C in UTF-8

$csv = $utfchar."x".$utfchar."x\n";

file_put_contents('test.csv', $csv);
$file = fopen('test.csv', 'r');
$data = fgetcsv($file);

for ($i = 0; $i < strlen($data[0]); $i++) {
    echo dechex(ord($data[0][$i])).' ';
}
echo "\n";
unlink('test.csv');

// expected: c3 89 78 c3 89 78 - "ÉxÉx"
// actual: 78 c3 89 78 - "xÉx"

?>
