G'day Raymond,

"Wide character ..."

I provided you with examples of ways to deal with this warning less than a fortnight ago; now you claim it's an issue you can't solve. Please go back and read what I wrote.

"No such script: 'CYRILIC' ..."

charnames shows "use charnames qw(cyrillic greek);". If you read the documentation, you should be able to fix this yourself.

"Global symbol "%s" requires explicit package name"

Search for that string in perldiag - Perl diagnostic messages to find out how to deal with it. I recommend you read perlintro - Perl introduction for beginners and use the diagnostics pragma while the meaning of these errors continues to elude you (they were explained to you in example 7.pl).

"No such class chr at 18.pl line 8, near "my chr""

Look at what you wrote at line 8; then look at the my documentation for the correct syntax.

"syntax error at 19.pl line 11, near "//,""

Look at line 11; then look near //. Can you spot the error?
