Hi,
if I copy a UNICODE string in the clipboard and paste it in a NVARCHAR2 column in the data grid of PL/SQL Developer only some of the first characters are stored. The strings are truncated at different positions. If I paste it in the data grid of Oracle SQL Developer it works and it is correctly displayed by PL/SQL Developer. The same problem occurs if I type the UNICODE string directly into the PL/SQL Developer data grid.
I am using 7.1.5.1396

Can you go to Help > Support Info, press the 'Copy all pages' button on this info screen, and paste this text into an e-mail reply?

Hello Marco,

Thank you.
