This is the full quote: "it is best to include either an explicit {$codepage xxx} directive or save the source code in UTF-8 with a BOM" (which I've now clarified a bit on the wiki page). Both are equally good as far as FPC is concerned.

Delphi doesn't know the {$codepage xxx} directive, but you can put it between {$ifdef fpc}. I don't know whether it automatically detects UTF-8-encoded files (or even handles them at all), especially these older versions. If it doesn't, you can still save your source code in any code page and add a {$codepage xxx} statement for FPC. Additionally, I forgot to mention that you can also specify the used code page on the command line with FPC, via the -Fc parameter.
