Ruby CSV BOM | StringIO 的 UTF-8 编码 rubycsvutf-8byte-order-markruby-csv 10 Ruby 2.6.3。 我一直在尝试将一个StringIO对象解析成具有bom|utf-8编码的CSV实例,以使BOM字符(不需要)被剥离并且内容被编码为UTF-8: require 'csv' CSV_READ_OPTIONS = { headers: true, encoding: 'bom|utf-8' }...
什么是BOM头(字节顺序标记(ByteOrderMark)) 在utf-8编码文件中BOM在文件头部,占用三个字节,用来标示该文件属于utf-8编码,现在已经有很多软件识别bom头,但是还有些不能识别bom头,比如PHP就不能识别bom头,这也是用记事本编辑utf-8编码后执行就会出错的原因了。其实UTF-8 的BOM对UFT-8没有作用,是为了支援UTF-16...

其中Unicode相关编码方式有3种,这3种编码方式的区别不再赘述,我们可以从文件的头部(即Windows中的特色!BOM:byte order mark)来区分一个文件是属于哪种编码。当头部开始的两个字节为 FF FE时,是UTF-16(LE)编码;当头部的两个字节为FEFF时,是UTF-16(BE)编码;当头部两个字节为EF BB时,是UTF-8-sig编码。
