Syntax using ebook-Covert in PHP

syntax either will make or break the routine

I set up the 1.48 version on a headless server because the server doesn't have the correct libs for the new version
regular call with nothing extra and hoping that the converter will do everything fine
exec("ebook-convert ".$INepub." ". $OutMobi." 2>&1 ",$output);

exec("ebook-convert ".$INepub." ". $OutMobi." --authors \"$Taname\" --publisher \"$pub\" --comments \"$comments\" --tags \"$tags\" --pubdate \"$pubdate\" --isbn \"$spidout\" --title \"$Ttitle\" 2>&1 ",$output);

The important part about this routine is that if you have any spaces in a string , you must escape the var or it will crash

AS well it does not handle UTF8 coding when sending so you have to strip any of that out from the var ahead of time

I use a function like this to do that
function ITSconvertchars( $str )
{
$str = str_replace( 'À', 'A', $str );
$str = str_replace( 'Á', 'A', $str );
$str = str_replace( 'Â', 'A', $str );
$str = str_replace( 'Ã', 'A', $str );
$str = str_replace( 'Ä', 'A', $str );
$str = str_replace( 'Å', 'A', $str );
$str = str_replace( 'Æ', 'A', $str );
$str = str_replace( 'Ç', 'C', $str );
$str = str_replace( 'È', 'E', $str );
$str = str_replace( 'É', 'E', $str );
$str = str_replace( 'Ê', 'E', $str );
$str = str_replace( 'Ë', 'E', $str );
$str = str_replace( 'Ì', 'I', $str );
$str = str_replace( 'Í', 'I', $str );

$str = str_replace( 'Ñ', 'N', $str );
$str = str_replace( 'Ò', 'O', $str );
