Francois,
Below you said: "Simply do a search and replace to change all
occurrences of String type to AnsiString type. The compiler will
automatically convert AnsiString to UnicodeString when it is necessary. This
will work although you will not
benefit from Unicode."
I realize I'm missing something obvious here, but why won't it
benefit from Unicode if the strings are converted?

Bad code. Always tell programmer to use the correct datatype for what he is
doing. If his code depends on strings being composed of ansi (8 bits)
characters, then always tell him to use AnsiString. This is true for many,
many versions now and for any strong typed language anyway. If his code
doesn't depends on character size, then it is OK to use string and it will
works unchanged with Delphi 2009.

Converting to C# would be tremendously more time consuming and you'll have
the risk to introduce a huge number of bugs because not only will you change
language but also all components and runtime.

Simply do a search and replace to change all occurences of String type to
AnsiString type. The compiler will automatically convert AnsiString to
UnicodeString when it is necessary. This will work altough you will not
benefit from Unicode.
By the way, if you need help porting old Delphi code to Delphi 2009, my
company provide such consulting services. Feel free to contact me by email.
