I'm trying to support a legacy multilingual website that has been upgraded to perl58 and now using PERLIO to properly encode html output. (STDOUT is mapped via binmode)
In an effort to only change a few globally included packages, rather than all the scripts or all the content, I like to find a way to associate a charset (other than utf8) dynamically to all FILE IO when building web pages from encoded templates.
The following works fine within the scope of the including package:
use open IN => ":encoding(shiftjis)";
open FILE,"cp_email_JPJA_sendemail.txt.sjis";
or something like
open (FILE,"<:utf8","cp_email_JPJA_sendemail.txt.utf8");
but I'd like to do something like use open IN => ":encoding(shiftjis)"; in a module that all application scripts and cgi's would include.
I've tried perllocale without success to at least produce UTF8 mapped file handles unilaterally:
use POSIX qw (locale_h);
use locale;
setlocale(LC_ALL,"en_US.UTF-8");
$ENV{LC_ALL} = $ENV{LANG} = 'UTF-8';
From perlunicode.html:
Usually locale settings and Unicode do not affect each other, but there are a couple of exceptions:
· If your locale environment variables (LANGUAGE, LC_ALL, LC_CTYPE, LANG) contain the strings 'UTF-8' or 'UTF8' (case-insensitive matching), the default encodings of your STDIN, STDOUT, and STDERR, and of any subsequent file open, are considered to be UTF-8.
· Perl tries really hard to work both with Unicode and the old byte-oriented world. Most often this is nice, but sometimes Perl's straddling of the proverbial fence causes problems.
As I said I can't seem to get this tweaked right to work. At least one could standardize on utf8 content and then output in whatever encoding was required.
Any thoughts would be greatly appreciated.
Here are system particulars:
