}

This is response from c# wcf service. We figure out that when the data have "ñ" , the encryption is incomplete.

I don't know it you are still needing a fix after all that time but here it is.
C# implementation does not work for non English cahracters.
After little bit of testing I have found the problem.
Code uses length of the string to encrypt data lenghth of the sting is expressed in characters which is not same as the array size generated by GetBytes method (it is the same using ASCII character only).

replace if statements in method EncryptDecrypt
....
if (mode.Equals(EncryptMode.Encrypt))
{
var encbytes = _enc.GetBytes(inputText);
//encrypt
byte[] plainText = _rcipher.CreateEncryptor().TransformFinalBlock(_enc.GetBytes(inputText), 0, encbytes.Length);
_out = Convert.ToBase64String(plainText);
}
if (mode.Equals(EncryptMode.Decrypt))
{
//decrypt
var decText = Convert.FromBase64String(inputText);
byte[] plainText = _rcipher.CreateDecryptor().TransformFinalBlock(decText, 0, decText.Length);
_out = _enc.GetString(plainText);
}
...
