String length
Hi I have a column varchar2(100). In the user interface I valiadted the input string only allow 100. But for one test case it passed the UI validation and failed in db insert with error ORA-12899: value too large for column (actual: 106, maximum: 100). I checked the string, only special thing is that (it copied from web browser) it has 2 single quote (’ by viewing the source) and 2 copyright sign (®). Are those causing the problem? How can I detect it? Thanks
