 Perl 5.8.0 also supports Unicode on EBCDIC platforms.  There,
 the Unicode support is somewhat more complex to implement since
 additional conversions are needed at every step.  Some problems

 In any case, the Unicode support on EBCDIC platforms is better than
 in the 5.6 series, which didn't work much at all for EBCDIC platform.
