procedure foo(a: Utf8String);

This will work only when "string" is UTF-16, since PChar is a pointer to
Unicode. You can try figure out what copies and conversions the compiler
may insert, in order to match the given casts and argument types.
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).
