Dear Monks

I'm sorting an array deaccenting its elements with Text::Unaccent::PurePerl.

Everything is fine except that my array happens to have now and then some undef elements which apparently is not accepted by Text::Unaccent::PurePerl (Error: unac_string: Input character string is undefined). Any way to turn - on the run - these undef elements let's say, to an empty string ""? My array comes from reading a SQLite database. What would be the approach you suggest?

@$ResultsFinal =( sort { unac_string($a->[($OptOrderToDisplayTable)]) 
+cmp unac_string($b->[($OptOrderToDisplayTable)])} @$ResultsFinal );
