Cant get ufpdf to work

#1
[eluser]bjora857[/eluser]
following the guide in
fpdf library

I was able to create a pdf using this code:

Code:
define('FPDF_FONTPATH',$this->config->item('fonts_path'));
    
    $this->load->library('fpdf');
    $this->fpdf->Open();
    $this->fpdf->AddPage();
    $this->fpdf->SetFont('Arial','B',14);
    $this->fpdf->SetY(30);
    $this->fpdf->Cell(40,10,'Faktura!');
    $this->fpdf->Cell(60,10,'åäö');

$this->fpdf->Output('output.pdf','D');

But there are no support for swedish letters: å ä ö.

So i downloaded ufpdf, I put the updfp.php in the library folder next to fpdf.php

Then I tried this code:
Code:
define('FPDF_FONTPATH',$this->config->item('fonts_path'));
    
    
    $this->load->library('ufpdf');
    $this->ufpdf->Open();
    $this->ufpdf->AddPage();
    $this->ufpdf->SetFont('Arial','B',14);
    $this->ufpdf->SetY(30);
    $this->ufpdf->Cell(40,10,'Faktura!');
    $this->ufpdf->Cell(60,10,'åäö');

$this->ufpdf->Output('output.pdf','D');

But it gives me lots of errors and no pdf...

A PHP Error was encountered
