Question

I have a String that has non ascii characters encoded as “\\’fc” (without quotes), where fc is hex 252 which corresponds to the german ü umlaut.

I managed to find all occurences and can replace them. But I have not been able to convert the fc to an ü.

"fc".hex.chr

gives me another representation…but if I do

puts "fc".hex.chr

I get nothing back…

Thanks in advance

PS: I’m working on ruby 1.9 and have

# coding: utf-8

at the top of the file.

Answer 1

Have you tried

puts "fc".hex.chr(Encoding::UTF_8)

Ruby docs:

• int.chr
• Encoding

UPDATE:

Jason True is right. fc is invalid UTF-8. I have no idea why my example works!
