How do I URI::encode
a string like:
\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a
to get it in a format like:
%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A
as per RFC 1738?
Here's what I tried:
irb(main):123:0> URI::encode "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a"
ArgumentError: invalid byte sequence in UTF-8
from /usr/local/lib/ruby/1.9.1/uri/common.rb:219:in `gsub'

from /usr/local/lib/ruby/1.9.1/uri/common.rb:505:in `escape'

from /usr/local/bin/irb:12:in `<main>'
Also:
irb(main):126:0> CGI::escape "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a"

I looked all about the internet and haven't found a way to do this, although I am almost positive that the other day I did this without any trouble at all.
str = "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a".force_encoding('ASCII-8BIT')
puts CGI.escape str
=> "%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A"
