ASP.NET Encrypt/decrypt and Unicode Encoding different strings lenghts - asp.net

Question

I've a mechanism of Encrypting and Decrypting in ASP.NET 4.6 / VB.NET
In Decrypting i use
.......
y="zoSObQFhc+GJSUrnAmagZ2/uuunFrCUv" ' String received
Dim cipherBytes As Byte() = Convert.FromBase64String(y)
Dim msDecrypt As MemoryStream = New MemoryStream(cipherBytes)
Dim csDecrypt As CryptoStream = New CryptoStream(msDecrypt, New TripleDESCryptoServiceProvider().CreateDecryptor(Key, IV), CryptoStreamMode.Read)
Dim fromEncrypt As Byte() = New Byte(cipherBytes.Length - 1) {}
csDecrypt.Read(fromEncrypt, 0, fromEncrypt.Length)
Dim x as string = Encoding.Unicode.GetString(fromEncrypt)
I passed a crypted (with variable y) string and the result is correct and get back the orinal word "procedure" (without quotes) in variable x.
Print x produces "procedure" (without quotes)
Only the Lenght of x is 12.
Now if try to check
if x = "procedure"....
Test is false.
Where i get wrong ?

Answer 1

After applying
System.Text.Encoding.UTF8.GetBytes(x).Select(Function(b) Hex(b)))
Results:
String Decrypted: 70 72 6F 63 65 64 75 72 61 0 0 0
Fixed String 70 72 6F 63 65 64 75 72 61
Following is all process to go and back (Enc/Dec)
