Я новый разработчик Android. Я'я работаю с латинским шрифтом в моем приложении, но я могузаставить его работать и продолжать получать? для персонажа. Мой код ниже, с использованием базы данных sqlite. Мне нужно извлечь текст из базы данных Sqlite и каждый специальный латинский символ (то есть à, ò, ù, è...) отображался с черными квадратами с "?" внутри.

Как я могу отобразить это правильно?

private void displayTestQuestion() {
    resetEverything();
    stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString(totalNumberOfQuestions));

    String questionText = questionCursor.getString(0);
    question.setText(Html.fromHtml(questionText));
    adjectiveNumber = questionCursor.getString(1);
    adjectiveCase = questionCursor.getString(3);
    adjectiveGender = questionCursor.getString(2);
}

Мой экран эмулятора: я

Мы также попробовали этот код:

private void displayTestQuestion() {
    resetEverything();
    stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString(totalNumberOfQuestions));

    String questionText = questionCursor.getString(0);
    Typeface font = Typeface.createFromAsset(questionCursor.getString(0), "fonts/LATINWD.TTF");
    //question.setText(Html.fromHtml(questionText));
    question.setText((CharSequence) font);
    adjectiveNumber = questionCursor.getString(1);
    adjectiveCase = questionCursor.getString(3);
    adjectiveGender = questionCursor.getString(2);
}

Но это дает мне следующую ошибку:

Метод createFromAsset (AssetManager, String) в типе Typeface не применим для аргументов (String, String).

И я использовал класс Sqlitehelper, мой код ниже:

public class VocabTesterDatabaseHelper extends SQLiteOpenHelper {

    private static String DB_PATH = "data/data/com.VoacabTester/databases/";

    private static String DB_NAME = "vocabdb.db";

    private SQLiteDatabase vocabDatabase;

    private final Context vocabContext;

    public VocabTesterDatabaseHelper(Context context) {
        super(context, DB_NAME, null, 3);
        this.vocabContext = context;
    }

            copyDataBase();
        }

    }

    private boolean checkDataBase() {

        File dbFile = new File(DB_PATH + DB_NAME);
        return dbFile.exists();
    }

    private void copyDataBase() throws IOException {
        try {

            InputStream myInput = vocabContext.getAssets().open(DB_NAME);
            String outFileName = DB_PATH + DB_NAME;

            // Open the empty db as the output stream
            OutputStream myOutput = new FileOutputStream(outFileName);

            byte[] buffer = new byte[1024];
            int length;
            while ((length = myInput.read(buffer)) > 0) {
                myOutput.write(buffer, 0, length);
            }
            myOutput.flush();
            myOutput.close();
            myInput.close();
        } catch (IOException e) {

        }
    }
