There was specific discussion about conversions relating to characters
in the range 0x80 through 0xff a few months ago. For parsing things like
APL and ALGOL character sets I specifically use UTF-16 internally, and
only convert to/from an 8-bit OEM codepage and/or UTF-8 at the margins
of the program.
See discussion in http://mantis.freepascal.org/view.php?id=21195 and
note change in the 2.7.1 compiler around revision 23613.
