One of the bugs fixed at the last release of the compiler was: "The character codes for << and >> (Continental European quotation marks)
were the wrong way around, following a mistake in version 0.2 of
the Z-Machine Standards document. They have therefore been
swapped over, following the correction made in version 1.0 of that document." Unfortunately, the fix is wrong, in that the Unicode values @{AB} and @{BB}
now produce the characters ">>" and "<<",
whereas they should display "<<" and ">>" respectively. The problem is associated with the default
zscii-to-unicode conversion table. If another table is used
(for example, by supplying the directive Zcharacter table '@{AB}' '@{BB}';),
then the characters print correctly. None submitted.
