Fix of issue with html tags inside RTL languages, space reversion shouldn't be performed on RTL strings. Consider next code:

Browse Source 
$pdf->SetFont('dejavusans', '', 14, '', false);
$pdf->setRTL(true);
$htmlhebrew = "אנ <b>לא</b> ודעת";
$pdf->WriteHTML($htmlhebrew, true, 0, true, 0);

it will output
אנלאודעת

with missing spaces around bold text לא

Expected output is:

אנ לא ודעת

with spaces around bold text לא
