In Toad 10.5, when trying to compile code that contains certain characters as Ãƒâ€šÃ , a Syntax Error (see below) is shown.
To reproduce the problem please follow the steps below:
1] Open Toad 10.5
2] Paste the code below to the SQL Editor and try to compile it
CREATE OR REPLACE PROCEDURE example
p_param VARCHAR2(01) := '''Ãƒâ€šÃ';
'[Error] Syntax check (3: 16): ERROR line 3, col 16, ending_line 3, ending_col 27: The string initializer has a value which is too long and toad will not compile the procedure.' is returned
Note that it is possible to compile this procedure with SQL Plus.
In Toad 10.1 you also receive the error when using F5 or control+enter but it is possible to compile it with F9 (ST70359)
Now in toad 10.5 it is not possible to compile it at all.
