Reading filename in multiple OS without encoding problem with Ruby
I want to get all filenames in UTF-8. For 开发者_运维知识库example, after I read filename in Windows, I do
filename = Iconv.iconv("UTF-8", "Windows-1251", filename)
In Ubuntu I don't convert filename and get it in UTF-8. Maybe exists some method to determine OS filename encoding?
I do this on Ruby 1.9 when I want to make sure things are in UTF-8:
if filename.encoding.to_s != 'UTF-8'
filename.encode!('UTF-8')
end
Unless your OS gives a file name encoded with a coding system which doesn't support some special characters found on the file name, it can be encoded to UTF-8 without a hickup.
