I want to check for col1 and col2 in my table given below for the cases where non keyboard characters are present.


    +------------+----------+
    |    col1    |    col2  |
    +------------+----------+
    | rewweew\s  |  4rtrt   |
    | é          |  é       |
    | 123/	     |  h|h     |
    | ëû	     |  û       |
    | ¼ 	     |  ¼       |
    | *&^	     |  *%$     |
    | #$         |  ~!`     |
    +------------+----------+


My desired result will look like

     +--------+-------+
     |   é    |   é   |
     |   ëû	  |   û   |
     |   ¼	  |   ¼   |
     +--------+-------+


In my case all characters present in English keyboard are allowed, i have to only find out row which have character not present in English keyboard like Chinese character etc.
