That are using various national eight-bit character sets, which would Not been made the default since there are many Perl scripts out there Itself has been written in the UTF-8 encoding of Unicode. The only remaining use of ``use utf8'' is when the Perl script To the data itself, and for most of the time ``use utf8'' is not neededĪt all. Unicode model has completely changed: now the ``Unicodeness'' is bound This was found to be an inconvenient interface, and in Perl 5.8 the Then the operations (like string concatenation) were Unicode-aware Previously in Perl 5.6 to use Unicode one would say ``use utf8'' and In general, the interfaces and implementation of Unicode support hasĬhanged significantly from the 5.6 release. New Unicode semantics (no more use utf8, almost) Pure Perl modules should continue to work, subject to the other Perl 5.8 is not binary compatible with earlier releases of Perl. Incompatible Changes in the perl582delta manpage, and Incompatible Changes in the perl584delta manpage, for additional minor incompatible changes made in Perl 5.8.1, Perl Please check Incompatible Changes in the perl581delta manpage, Be sure to consider these very carefully before upgrading. The following list is a general summary of the known incompatibilitiesīetween the Perl 5.8.0 source code release and earlier releases based on Windows x86 for Windows 9x, NT, Me, 2000, XP and 2003įor a chronological list of changes included in this and past releases, In particular, do not attempt to useĮxtensions or PPM packages built for the 600 and 500 series builds withĪctivePerl 800 series builds and vice versa. Please note that ActivePerl 800 series builds are NOT binary-compatible with I believe the original underlying issue was something to do with different PATH variables for 32-bit and 64-bit environments and possibly some internal Windows redirection that takes place automatically.Welcome, and thanks for downloading ActivePerl. If you had a PowerShell window open before setting the PATH variable, you will need to close it and re-open another instance of PowerShell. That fixed it and entering 'perl -v' into command prompt successfully replies your Perl version. (The directory paths are for the 64 bit edition of Perl, adjust according to your installation) the %PATH% portion is important and ensures your existing settings are kept and not wiped out and overwritten when you set the PATH. So to remedy that I entered this into the command prompt and hit enter: set PATH=C:\Perl64\bin C:\Perl64\site\bin %PATH% I tried installing 'Microsoft Visual C++ 2008 x86 and 圆4 redistributable setup' files as suggested by a few places but it still did not resolve the issue, until I tried some of the suggestions in this thread.Īt the command prompt I entered: set PATHĪnd surprisingly it did not list the Perl directories as being included in the PATH variables. I remember selecting the option during installation to add the Perl directory to the system PATH environment, and after checking the system properties, it was indeed showing in the system PATH. 'perl' is not recognized as an internal or external command, operable I was getting a similar error after installing ActiveState Perl on Windows 8 圆4 bit edition and trying to invoke 'perl' at the command line.
