help with utf-8 BOM's and smarty

hi everyone,

i'm new to smarty templates and its really nice, but one thing i need to add.
i need to add this function to eliminate BOM's from templates before start compiling .

function removeBOM($str=""){
if(substr($str, 0,3) == pack("CCC",0xef,0xbb,0xbf)) {
$str=substr($str, 3);
}
return $str;
}
I suppose it must be somewhere in "fetch()" but I cant figure exactly where to put this function to work properly. can anyone help me with that??

is it too hard to figure it out !! please share yout idea what ever it was. it will be apreciated.

I am looking at Smarty v2.6.19 (most recent version).

Open Smarty.class.php and scroll to the method _read_file() on line 1707:

/**
* read in a file
*
* @param string $filename
* @return string
*/
function _read_file($filename)
{
if ( file_exists($filename) && ($fd = @fopen($filename, 'rb')) ) {
$contents = '';
while (!feof($fd)) {
$contents .= fread($fd, 8192);
}
fclose($fd);
return $contents;
} else {
return false;
}
}


Replace it with this one:

/**
* read in a file
*
* @param string $filename
* @return string
*/
function _read_file($filename)
{
if ( file_exists($filename) && ($fd = @fopen($filename, 'rb')) ) {
$contents = '';
while (!feof($fd)) {
$contents .= fread($fd, 8192);
}
fclose($fd);
$contents = removeBOM( $contents ); // customization: remove byte-order marks
return $contents;
} else {
return false;
}
}


Untested, but it should do what you're looking to accomplish.
