Maybe the font has a problem, what you would do is find the character that corresponds to that maybe é É are invested and be wrong and replace the character with the correct
str.replace ('é', 'É');
where str is your string
That's no option for me, because the title is also displayed as title on the website and it is displayed correctly. The title will be integrated automatically in the player.
No problem, your data source does not have to be altered, only flash when receiving the information, would have to change it, another solution is to use a program to repair the font
