Thought they were defined in an ASCII table with some specific ISO number?

ASCII for Japanese character that should not be entered...and how to handle it in the event...Since we have to use Shift+ when we type in English n Japanese(virtual Keyboard)

I think Japnese characters fits in Multbyte, not in ASCII.

Seems to be in UTF8 profile, no?

So we should identify whether the input character two byte character and they avoid it in textbox is it... is there any other way like we check in keypress for alpha numeric character check...

Asc or WAsc i think... Its suppose to give you the ASCII code...
