FinalBuilder uses ANSI as the default encoding for actions such as ‘Create Text File’. Imo, this should be changed to UTF-8 (no BOM) nowadays. This has caused issues for us, as developers often get caught by this trap.
The most common file type still using ANSI is a Windows INI-File. FinalBuilder uses the ANSI encoding for them implicit. So that is working correctly, unless you store the content as UTF-8. This is actually an issue too, as most editors use UTF-8 as default. Maybe the FinalBuilder dialogs should display the encoding used as a readonly item. Just to make a developer aware of the issue.
