How to create a file with UTF-8 encoding

[Jin Lee]

Hi, as known that the default encoding is set to ANSI when creating a
text file. How can I specify the encoding type to UTF-8 other than ANSI
when creating a text file in RUBY? Thanks a lot.

I've tried the ways found by google, but no available. E.g.
tst = File.new("abc.txt","w:UTF-8")
There is an error message: illegal access mode w:UTF-8 (ArgumentError)

Please help me if there is another way to work it out, thanks.

Thanks Robert, the version of mine is 1.8.6 (2007-09-24 patchlevel 111)

It seems that this encoding option is only supported in 1.9?

Thanks again, it's talking about encodings in 1.9.

So how can I get it work in previous versions, such as 1.8.6?
