当我从文件中读取内容时,有时会出现此错误" UTF-8中的无效字节序列 ".注意 - 只有在字符串中有一些特殊字符时才会发生这种情况.我试过没有"r:UTF-8"打开文件,但仍然得到相同的错误.

open(file, "r:UTF-8").each_line { |line| puts line.strip(",") } # line.strip generates the error

文件内容:

# encoding: UTF-8
290919,"SE","26","Sk‰l","",59.4500,17.9500,, # this errors out
290956,"CZ","45","HornÌ Bradlo","",49.8000,15.7500,, # this errors out
290958,"NO","02","Svaland","",58.4000,8.0500,, # this works

这是我从外面获得的CSV文件,我试图将其导入我的数据库,它顶部没有"#encoding:UTF-8",但我添加了这个,因为我读到了某处它将解决这个问题,但事实并非如此.:(
