fix the way unicode character are displayed in generated responses in…

[imami]

A little change, to show correct unicode characters that example responses might have instead of the way the are now in escaped.

For example:

{"name":"\u0627\u0628\u0631\u0627\u0647\u06cc\u0645"}

should be displayed as :

{"name":"ابراهیم"}

to be readable in documents.
