OB的locale 与 FB/NB 的locale 是一回事么？说OB不支持locale，但具体设置上不是与FB/NB很类似么？都是设置 LC_*** 的环境变量。在线manual：

NAME
locale - Perl pragma to use and avoid POSIX locales for built-in
operations
SYNOPSIS
@x = sort @y; # ASCII sorting order
{
use locale;
@x = sort @y; # Locale-defined sorting order
}
@x = sort @y; # ASCII sorting order again
DESCRIPTION
This pragma tells the compiler to enable (or disable) the use of POSIX
locales for built-in operations (LC_CTYPE for regular expressions, and
LC_COLLATE for string comparison). Each "use locale" or "no locale"
affects statements to the end of the enclosing BLOCK.
See perllocale for more detailed information on how Perl supports
locales.
