pdf使用php和drupal进行文本转换

i am using this code for conversion pdf to text, it is working fine but it is not support swedish character, like:

correect swedish word     = incorrect word    
Förnamn                   = Fšrnamn,
Försäljningsdatum         = FšrsŠljningsdatum,
varumärket                = varumŠrket,
terförsäljaruppgifter     = terfšrsŠljaruppgifter

code is:

<?php
    require_once "pdf.pdf2text.inc";
    $filename = "customerfile.pdf";
    $pdf = new Pdf(urldecode($filename));
    print utf8_decode($pdf->getText());//with utf-8
    print $pdf->getText(); //without utf-8
?>

i am added utf-8 encoded/decoded but its not working. using this code

please anybody help me or suggest me to show proper text (Words) using this code.

thanks in advance.

iconv(); might be a possibility http://php.net/manual/fr/function.utf8-decode.php

$myUnicodeString = "Åäö"; echo iconv("UTF-8", "ISO-8859-1", $myUnicodeString); as some comments say UTF-8_decode(); is not enough to handle accents.

According to a comment on Drupal.org from Saubhagya:

add the octal and unicode equivalents of desired characters in array $_pdfDocToUni line 18 file initialize.pdf2text.inc (remember octal need to be in 3 digits as in other entries of array).

Then just go to line 335 of pdf2text.module and add your character in the same format of other ones.

Not sure about the use of the word "just" but it might be a help...

This appears to be the module he is talking about and it does have the array he mentioned - perhaps your version may have modules missing - there seem to be a lot of them on offer
