hope this fix your issue Colors.valueOf("R") is a implicitly declared method and a shortcut of Enum.valueOf(Colors.class, "R").

I wish did fix the issue. I need to compare single char to char array and see if array has that char. , Let's see if I got what you need :
code :
public void actionPerformed(ActionEvent e) {
    String action = e.getActionCommand();
    if (action == "Guess Letter"){
        inputChar = JOptionPane.showInputDialog("Please enter letter (a-z)");
        if (inputChar.length() > 1){ //User input is a string here, right?
            GuessedLetters glr = new GuessedLetters(inputChar);
            glr.setInString(inputChar);
            System.out.println(wordToGuess.contains(glr.getInString())); //This will print true if wordToGuess is equal to glr.getInString() or if it just contains it
            //For testing purposes
            System.out.println("This is String: " +glr.getInString());              
        }else{ //Here the user gave us just a character, so we've got to know if this character is contained in the word, right?
        GuessedLetters glr = new GuessedLetters(inputChar);
        glr.setInChar(inputChar);
        System.out.println(wordToGuess.contains(glr.getInChar()); //This will print true if your char is in the wordToGuess string
        //For testing purposes
        System.out.println("This is Char: " +glr.getInChar());
        }
    }
}

around this issue I've a form with Primefaces. The header of the xml file looks like that: , You need to tell the HttpServletRequest instance that it's in UTF-8:
code :
public String handleRequest(HttpServletRequest request) {    
   try {
       request.setCharacterEncoding("UTF-8");
       String shortname = request.getParameter("shortname");

       (...)
   }
   catch (UnsupportedEncodingException e) {
       // ...
   }
}

Does that help I have this simple enum in Java , Renamed type to name to avoid confusion, but you got the idea.
code :
public enum FileType 
{
    FILE('-'), DIRECTORY('d'), SYMLINK('l'), DEVICE('b');

    private char name;

    FileType(char name) 
    {
        this.name = name;
    }

    public static FileType getFileTypeForName(final char name)
    {
        for (FileType type : FileType.values())
            if (type.name == name)
                return type;

        return null;
    }
}

Java Decode double encoded utf-8 char

I wish this helpful for you You text was encoding to UTF-8, those bytes were then interpreted as ISO-8859-1 and re-encoded to UTF-8.
Wrocławskiej is unicode: 0057 0072 006f 0063 0142 0061 0077 0073 006b 0069 0065 006a
code :
String s = new String(bytes, StandardCharsets.UTF_8);

// fix "double encoding"
s = new String(s.getBytes(StandardCharsets.ISO_8859_1), StandardCharsets.UTF_8);
