Hi,
It might be too long after last message on this discussion but I thought it might be usefull to somebody else.
I am using FengOffice 1.7.5 and tried to produce PDF reports with Greek characters: all the Greek characters were missing from the PDF file.
It seems that the problem lies in application/controllers/ReportingController.class.php and the function generatePDFReport($report, $results). In version 1.7.5 lines 963, 1005 and 1028 look like:
$YYYY = iconv(mb_internal_encoding(), "ISO-8859-1", html_entity_decode($XXXX, ENT_COMPAT));.
At situations like this it is really usefull to add a line like:
Logger::log("INTERNAL ENCODING = " . mb_internal_encoding(),Logger::INFO);
after one of those lines, produce a PDF report and check the output in cache/log.php (check for lines marked with INFO). In my case it confirmed that I use UTF-8 and what lines did was to convert UTF-8 to ISO-8859-1 which is not really what one would like to do for Greek or Chinese.
After some investigation i figured out that the implementation of generatePDFReport($report, $results) is non-UTF-8 for a good reason: the PDF library shipped with FengOffice is NOT a UTF-8 compatible library. There is a UTF-8 alternative version tfpdf. It is easy to use it since you simply have to download it to the libraries folder and edit the function generatePDFReport($report, $results):
$pdf = new tFPDF(); and
$pdf->AddFont('DejaVu','','DejaVuSansCondensed.ttf',true);
$pdf->SetFont('DejaVu','',$fontSize);
In my case this solution did not work since the font definition files (e.g.
library/tfpdf/font/unifont/dejavusans.cw.dat
library/tfpdf/font/unifont/dejavusans.mtx.php)
are generated on the fly for the first time and I was getting problems I could not bother to resolve.
I decided to use the TCPDF library which seems to have a better Unicode support (well, I have seen it on other php based systems and at first I tried to cheat using its font definitions with TFPDF but this seemed more complicated than switching to TCPDF).
The solution is relatively simple:
1. Unzip the library downloaded from in the libraries folder
2. Change the function generatePDFReport($report, $results)
function generatePDFReport($report, $results){
$types = self::get_report_column_types($report->getId());
eval('$managerInstance = ' . $report->getObjectType() . "::instance();");
$externalCols = $managerInstance->getExternalColumns();
$filename = str_replace(' ', '_',$report->getName()).date('_YmdHis');
$pageLayout = $_POST['pdfPageLayout'];
$fontSize = $_POST['pdfFontSize'];
include_once(LIBRARY_PATH . '/tcpdf/config/lang/eng.php');
include_once(LIBRARY_PATH . '/tcpdf/tcpdf.php');
$pdf = new TCPDF($pageLayout, 'mm', 'A4', true, 'UTF-8', false);
$pdf->setTitle($report->getName());
$pdf->SetFont('dejavusans','',$fontSize);
$pdf->AddPage();
