I am using react-native-simple-encryption to encrypt and decrypt strings in my react-native application also on my web application, which works fine on english alphabet and many other chars but i am having trouble on encrypting and decrypting some Turkish letters for example "ş" and "Ş" or "ğ" and "Ğ" won't be the same when encrypted and decrypted, i have tried adding those chars to b64Table but that didn't solve my problem.Is there another solution i can try for this problem?
