This may or may not be a problem with ancient TCP/IP stacks of VMS: we do not know since we weren't able to test Perl in such configurations. +=head2 Different Definition of the Unicode Character Classes \p{In...} + +As suggested by the Unicode consortium, the Unicode character classes +now prefer I<scripts> as opposed to I<blocks> (as defined by Unicode); +in Perl, when the C<\p{In....}> and the C<\p{In....}> regular expression +constructs are used. This has changed the definition of some of those +character classes. + +The difference between scripts and blocks is that scripts are the +glyphs used by a language or a group of languages, while the blocks +are more artificial groupings of 256 characters based on the Unicode +numbering. + +In general this change results in more inclusive Unicode character +classes, but changes to the other direction also do take place: +for example while the script C<Latin> includes all the Latin +characters and their various diacritic-adorned versions, it +does not include the various punctuation or digits (since they +are not solely C<Latin>). + +Changes in the character class semantics may have happened if a script +and a block happen to have the same name, for example C<Hebrew>. +In such cases the script wins and C<\p{InHebrew}> now means the script +definition of Hebrew. The block definition in still available, +though, by appending C<Block> to the name: C<\p{InHebrewBlock}> means +what C<\p{InHebrew}> meant in perl 5.6.0.
