It can be either, but it's probably the widestring manager in this case (it uses a question mark to replace characters that cannot be represented in the current character set; this is detected by the OS' widestring manager returning an error, or in certain cases the the OS' widestring conversion routines themselves will replace unrepresentable characters with '?').

If you are on a Unix platform, remember to add the "cwstring" unit to your uses clause.
