OK, I figured out what happened. The source file was saved in UTF-8
encoding, but I hadn't put in my source file the compiler directive
{$CODEPAGE UTF8}. After including this directive in my code almost
everything worked fine: length() was returning the right number of
unicode characters, and subscripting the widestring returned the right
character. But as the widechar and widestring encoding is, as you said,
UTF-16, while my Mac OS X console uses UTF-8 encoding, for the output
results to be displayed correctly I had to wrap the individual widechars
or the whole widestring with the function utf8encode(), prior to output
them with write()...
Thanks for your help,
Christos
