我想要做的是获取所有UTF16 Unicode图表的集合.我从http://unicode.org/charts/PDF/下载了所有pdf文件,并决定使用perl来删除所有特殊或UTF32图表,其中包含以下脚本:
#!/usr/bin/perl
opendir(my $dir, ".");
my @files = grep {!/^U[0-9,A-F]{4}\.pdf/ && !/utf16only.pl/} readdir($dir);
for $f (@files)
{
print "deleting $f...\n";
#unlink $f;
}
closedir($dir);
当我运行脚本时,我得到以下输出:
C:\Users\Evan\Downloads\Unicode 6.1 Charts>utf16only.pl
