我有以下测试:
use Test::More;
use Lingua::EN::NameCase 'nc';
use utf8;
my $output = Test::Builder->new->todo_output;
binmode $output, ':encoding(UTF-8)';
$output = Test::Builder->new->failure_output;
binmode $output, ':encoding(UTF-8)';
my $name = 'Lintão';
is nc($name), $name, 'nc() should not change a properly namecased name';
diag nc($name);
done_testing;
在带有Perl 5.10.1的Mac OS X上,我得到以下输出:
nc.t ..
ok 1 - nc() should not change a properly namecased name
1..1
# Lintão
ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.02 usr 0.01 sys + 0.04 cusr 0.00 csys = 0.07 CPU)
Result: PASS
不幸的是,在 Debian Squeezebox 上用 5.10.1 Perl 进行的相同测试会产生以下输出:
nc.t ..
not ok 1 - nc() should not change a properly namecased name
# Failed test 'nc() should not change a properly namecased name'
# at nc.t line 10.
# got: 'LintãO'
# expected: 'Lintão'
# LintãO
1..1
# Looks like you failed 1 test of 1.
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/1 subtests

子例程中的违规行似乎是这样的:
s{ b (w) }{u$1}gox ; # Uppercase first letter of every word.
所以不知何故,Debian 上相同版本的 Perl 弄错了边界这个词。谁能帮我进一步调试?
Linux
盒子上的区域设置不考虑ã
单词字符(Lingua::EN::NameCase
use locale;
,因此它使用当前的LC_CTYPE
设置进行字符分类)。对于从 5.8.1 到 5.18.1 的 perlbrewed perls,我在 Ubuntu 12.04 LTS 上使用en_GB.UTF-8
语言环境一致地获得此输出:
$ perl -Mutf8 -le 'print 0+("ã" =~ /w/); use locale; print 0+("ã" =~ /w/)'
