That's because you don't use the cwstring unit nor another widestring  
manager. In that case, the DefaultSystemCodePage is set to ASCII  
because the default string conversion routines on Unix platforms do  
not support anything else (neither for converting from  
ansi/shortstring to wide/unicodestring, nor between ansistrings using  
different codepages). This is not new with FPC 3.0, it has always been  
like that.
