One of the systems I look after receives daily csv files from a third party. Recently the integration stopped working. I managed to pinpoint root the cause - the curly apostrophe. Once replaced with a regular one import files got processed successfully.
Third party system that generates these files is one of the Microsoft products, MS Access I think. System that receive and process these files is written in PHP on MySql database.
And here are the questions I would like to ask here: - is this PHP or MySql that does not 'like' this character? - are there any more characters of this kind that php/mysql would have issue processing?
