Hi Loganathan,

I guess this might help you with your issue.

Try using this helper:

http://snippets.dzone.com/posts/show/4527

It puts a method utf8? on the String. So you can grab the String from mysql and see if it is utf8:

my_string.utf8?

If is not, then you can try change the encoding of your String using other methods like:

my_string.asciify_utf8

my_string.latin1_to_utf8

my_string.cp1252_to_utf8

my_string.utf16le_to_utf8

Maybe this String is saved on mysql in one of these encodings.
