[Solved] SetCodePage can raise an exception?
« on: December 25, 2022, 12:35:20 pm »
SetCodePage calls fpc_AnsiStr_To_AnsiStr, I cannot find its code in 'fpcsrc' yet. Can it raise an exception (or set another error flag) on conversion error? I need that exception - my app wants to check is some encoding applicable to a file or not.

PS. I found the source - fpc_AnsiStr_To_AnsiStr calls widestringmanager methods. But I cannot find their src yet.

The sources for the default widestring manager are in rtl.

AFAICS by testing it will return an empty string if it cannot convert.

Someone with more knowledge (an fpc devel) should confirm this.
My conclusion is based upon very limited testing!

I have the same conclusion as Bart, also after very limited testing, but I am not a devel.
Anyway, you can write your own exception handler if empty.
