French characters are not properly displayed in PDF created using PHP FPDF class

Problem in displaying French characters or other language characters that uses latin scripts  on PDF files generated using FPDF class

I am using FPDF class Version 1.6 to generate a pdf file which have french characters in it. But on the PDF file the french characters are either discarded or displayed as some other unfamiliar characters.

Solution:

I tried the below given script to fix the issue.

===============


function change_encoding($str){
return( iconv("UTF-8", "CP1250//TRANSLIT", $str) );
}

===============

The function given above will accept a string and generate the french character friendly encded string.

string iconv ( string $in_charset , string $out_charset , string $str )

the function iconv converts a string to requested character encoding. It performs a character set conversion on the string "$str" from "in_charset" to "out_charset".

Use of TRANSLIT and IGNORE

Appending "//TRANSLIT" to out_charset transliteration is activated. This means that when a character can't be represented in the target charset, it can be approximated through one or several similarly looking characters.

Appending "//IGNORE", characters that cannot be represented in the target charset are silently discarded.

Otherwise, $str is cut from the first illegal character and an E_NOTICE is generated.
{source.php.net}


So Indorder to write a french string on to a Cell in the PDF file call the function like this:

==============

$pdf->Cell(35,5, change_encoding($YourFrenchString),0,1,'',0,'');

==============
