Well, you can type basically any characters if you change the language settings of your device's keyboard. (if that keyboard app supports it, that is...) I just used my favourite/default keyboard app Swiftkey to input some Greek characters, for the same reason.
Apart from that (especially if the character set is so cryptic that you cannot identify the language), you might try to use something like Google goggles/Translator to read it from a screenshot and create a search from it.
But I don't know if it's worth THAT much effort. After all, knowing the opponent's overall strength doesn't really help you - you need to decide for each defending team whether you can beat them or not.
