    何曾几时本猫还在windows下编码的时候,那时ruby的源代码的编码格式都是gbk啊!导致N多中文显示为乱码。后来无奈写了个转换代码从gbk编码转为utf-8格式的小工具:

#!/usr/bin/ruby
#tool 4 gbk encoding to utf8 

src_path = $*[0]
unless src_path
	puts "usage #{$0[2..-1]} gbk_file"
	exit 1
end

dir_name,base_name = File.split(src_path)
dst_path = dir_name << '/u8_' << base_name
f_src = File.open(src_path,"r:gbk")
f_dst = File.open(dst_path,"w:utf-8")

f_src.each_with_index do |line,i|
	line.encode!("utf-8")
	if(i < 2)
		#line.gsub!(/gbk/,"utf-8") if(line =~ /^#[ ]*coding*/)
		line.gsub!(/gbk/,"utf-8") if(line =~ /^*coding*/)
	end
	f_dst.puts line
end

f_src.close
f_dst.close
`chmod +x #{dst_path}`

再后来发现mac系统下自带iconv这个好东东啊:

ICONV(1)                   Linux Programmer‘s Manual                  ICONV(1)


NAME

       iconv - character set conversion


SYNOPSIS

       iconv [OPTION...] [-f encoding] [-t encoding] [inputfile ...]

       iconv -l


DESCRIPTION

       The  iconv program converts text from one encoding to another encoding.

       More precisely, it converts from the encoding given for the  -f  option

       to  the  encoding  given  for  the -t option. Either of these encodings

       defaults to the encoding of the current locale. All the inputfiles  are

       read  and  converted  in  turn;  if no inputfile is given, the standard

       input is used. The converted text is printed to standard output.


       The encodings permitted are system dependent. For the  libiconv  imple-

       mentation, they are listed in the iconv_open(3) manual page.


       Options controlling the input and output format:


       -f encoding, --from-code=encoding

我们来试一下,创建一个utf-8格式的文本:

路人甲:最近又多学了德语,现在懂中文,英语和德语啊
猫猫:靠,我早精通十几门语言了
路人甲:擦,我才不信
猫猫:汇编语言,C语言,C++语言,C#语言,ruby语言,javascript语言...
路人甲:...

用iconv转换为gbk格式(或者反向转换也可以):

apple@kissAir: ruby_src$iconv -f UTF-8 -t GBK ex_u8.txt > ex_gbk.txt

apple@kissAir: ruby_src$cat ex_gbk.txt

·???:????????????????????????????

èè?????????羫????????????

·??????????????

èè?????????,C????,C++?????C#????,ruby????,javascript????...

·???:...apple@kissAir: ruby_src$

我们可以看一下iconv到底支持多少种编码格式,貌似是超多的啊:

apple@kissAir: ruby_src$iconv -l

最后说点题外话,夸一下UNIX系统的整体性和统一性,这种统一性带来学习成本的急剧下降,而且让人很有成就感。比如我在ruby中知道正则表达式最后加i表示忽略大小写,我有次用grep查找的时候发觉也要忽略大小写查找,你猜猜我用神马选项:grep -i xxx,就是这么统一,这么和谐。windows下可以吗?哦,对了windows下人家不玩console,人家都玩窗口...
