R – Does Delphi ‘s REGION directive support a default ‘folded’ attribute

I'm assuming D7 doesn't want to copile {$REGION} or {$ENDREGION}? I only have D2007/9 installed and cannot check that.

Try this:

{$IFDEF undef}{$REGION 'bla'}{$ENDIF}
//some code
{$IFDEF undef}{$ENDREGION}{$ENDIF}

D2009 editor creates a region as expected. D7 should ignore the $REGION/$ENDREGION if 'undef' is not defined.

In fact this blog post from 2004 mentions a hidden IDE option. It states that you can set a default file filter in the registry to make UTF-8 the default encoding in Delphi 8. This still works under Tokyo! Clearly, you have to adapt the path of the registry key to recent versions like this:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Embarcadero\BDS\19.0\Editor]
"DefaultFileFilter"="Borland.FileFilter.UTF8ToUTF8"

After setting this value Delphi will encode new units in UTF-8 with BOM.
