As an offshoot from #42 there was one issue in which 'abhI' was sorted separately.
I examined it. There seem to be some conversion error while converting it to devanAgarI, because the json_encode gives 'null' in that case.
Error was in multi13.php on the following line
$delimiters = " \-*()@\ ";
There was a long dash in between which was causing problem in conversion.
Now cleaned up.
