You do know that currently PChar is still a PAnsiChar? Also there was no 
final decision whether "mode ObjFPC" will have String defined as 
UnicodeString or not. It only seems to be the case that there will be a 
mode "DelphiUnicode" where this is true (and maybe a modeswitch 
"unicodestrings" like was done for the JVM port).
