How to ensure that Strings are in UTF-8?

Question

How to convert this String the surveyÂ’s rules to UTF-8 in Scala?

I tried these roads but does not work:

scala> val text =         


        

Answer 1

Just set the JVM's file.encoding parameter to UTF-8 as follows:

-Dfile.encoding=UTF-8

It makes sure that UTF-8 is the default encoding.

Using scala it could be scala -Dfile.encoding=UTF-8.
