hpricto不支持gb2312,iconv后还是个报错

报错信息  in `<main>': "\x90" on GB2312 (Encoding::InvalidByteSequenceError)

不加

1. if RUBY_VERSION =~ /1.9/
   
2.   Encoding.default_external = Encoding::UTF_8
   
3.   Encoding.default_internal = Encoding::UTF_8
   
4. end

复制代码

这个头报的错不一样

Ruby193/lib/ruby/gems/1.9.1/gems/hpricot-0.8.6-x86-mswin32/lib/hpricot/builder.rb:9:in `gsub': invalid byte sequence in GBK (ArgumentError)

这个头搞得代码好难看

yakczh

加了

1. if RUBY_VERSION =~ /1.9/
   
2. 
   
3.   Encoding.default_external = Encoding::UTF_8
   
4. 
   
5.   Encoding.default_internal = Encoding::UTF_8
   
6. 
   
7. end

复制代码

以后还需要在文件头指定

1. #encoding: utf-8  
   

复制代码

文件编码吗?
