如题:
有人见过： >export PERL5OPT=-CA  这句怎么用吗？

我正在找perl cgi程序 执行 shell 相关命令时，使用utf-8 编码，
这样或许能解决我的手动操作、单cgi脚本操作该命令，输出中文内容正常；html调用cgi脚本后，输出中文内容异常的现象。

PERL5OPT

1. Command-line options (switches). Switches in this variable are treated as if they were on every Perl command line.
   
2. 
   
3. Only the -[CDIMUdmtwW] switches are allowed.
   
4. 
   
5. When running taint checks (either because the program was running setuid or setgid, or because the -T or -t switch was used), this variable is ignored. If PERL5OPT begins with -T, tainting will be enabled and subsequent options ignored. If PERL5OPT begins with -t, tainting will be enabled, a writable dot removed from @INC, and subsequent options honored.

1. -C [number/list]
   
2. 
   
3. The -C flag controls some of the Perl Unicode features.
   
4. 
   
5. As of 5.8.1, the -C can be followed either by a number or a list of option letters. The letters, their numeric values, and effects are as follows; listing the letters is equal to summing the numbers.
   
6. 
   
7.     I 1 STDIN is assumed to be in UTF-8
   
8.     O 2 STDOUT will be in UTF-8
   
9.     E 4 STDERR will be in UTF-8
   
10.     S 7 I + O + E
    
11.     i 8 UTF-8 is the default PerlIO layer for input streams
    
12.     o 16 UTF-8 is the default PerlIO layer for output streams
    
13.     D 24 i + o
    
14.     A 32 the @ARGV elements are expected to be strings encoded
    
15.     in UTF-8
    
16.     L 64 normally the "IOEioA" are unconditional, the L makes
    
17.     them conditional on the locale environment variables
    
18.     (the LC_ALL, LC_TYPE, and LANG, in the order of
    
19.     decreasing precedence) -- if the variables indicate
    
20.     UTF-8, then the selected "IOEioA" are in effect
    
21.     a 256 Set ${^UTF8CACHE} to -1, to run the UTF-8 caching
    
22.     code in debugging mode.
