Hi, I'm an iPhone developer. I'm writing my unit test cases, one of which checks if the app accepts UTF8 strings to be written to a sqlite3 database. I created a test case to generate random UTF8 strings and I can see the ones that fail do so because they contain an apostrophe (') which I need to be accepted. I'm writing to the databa...
