Unicode (\u) e.g "abhi\ushek" in a column value disables copy option

In one of the data table column the value is like "abhi\ushek"
"copy, csv, excel,pdf" doesn't work fr datatable if table contains values like "abhi\ushek"

if table doesn't contain value \u then copy,pdf,csv etc works fine. please suggest.
