Ruby 1.8.7中的String.encode（）替代品，用于清理对UTF-8的输入

Question

I just discovered that the String.encode method is only available from Ruby -v 1.9.3 and upwards. I'm working in a Rails environment were I cannot change this. I used this method to correct invalid UTF-8 input.

The only good alternative I've found was through the iconv.conv() method, however iconv is deprecated in newer ruby versions and I would like my code to be smelling like flowers even if/when my sysadmin decides to upgrade.

For reference, the alternative I found from Here :

ic = Iconv.new('UTF-8//IGNORE', 'UTF-8')
valid_string = ic.iconv(untrusted_string + ' ')[0..-2]

Thanks!

看一下charlock_holmes gem，它满足了1.9版之前的大多数编码要求。
