Support configurable formula escaping character for csv export?

[alexyang2920]

Currently, JasperReports uses a space character to escape formulas in CSV files to prevent CSV injection. You can see the implementation details here.
It would be beneficial if JasperReports allowed users to configure the escape character.

Hi @alexyang2920 ,
could you please let us know more details (some use cases maybe) about the necessity of a configurable escape character?

Thank you,

Originally we were thinking if we could prepending a single quote which could be hidden in excel, however it looks like the single quote still shows unless you double click the excel cell, however it's still be good to make it configurable in case someone want to use single quote or other characters.
