Question

I try to output the german setence containing the letter “ü” in escaped form (ascii 252, octal 374, hex 0xfc) using the following code:

pp "Test \374"
pp "Test \374".encode("UTF-8")

But using ruby 1.8.7 I get:
“Test \374”
“Test \374”

Using ruby 1.9.2 outputs:
“Test \xFC”
“Test \xFC”

How can I get ruby (1.8.7 + 1.9.x) to output “Test ü”? 🙂

Answer 1

>> pp "Test \xc3\xbc"
"Test ü"
=> nil

>> s="Test \374"  # This has utf-8 encoding but we need it to be "ISO-8859-1"
=> "Test \xFC"
>> s.force_encoding("ISO-8859-1")
=> "Test "
>> s.encode("UTF-8")
=> "Test ü"
