utf-8

Trying to convert output from a rest_client GET to the characters that are represented with escape sequences.

Input: ..."sub_id":"\u0d9c\u8138\u8134\u3f30\u8139\u2b71"...

(which I put in 'all_subs')

Match: m = /sub_id\"\:\"([^\"]+)\"/.match(all_subs.to_str) [1]

Print: puts m.force_encoding("UTF-8").unpack('U*').pack('U*')

But it just comes out the same way I put it in. ie, "\u0d9c\u8138\u8134\u3f30\u8139\u2b71"

However, if I convert a raw string of it:

puts "\u0d9c\u8138\u8134\u3f30\u8139\u2b71".unpack('U*').pack('U*')

The output is perfect as "??????"

How can I tell if a CSV is in UTF-7 or UTF-8

Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option). Using .NET… >>> More
