Hi, I've come across two lines of code that I can't get to work, even using an alternate code.
The idea was to store small images in a Postgresql database in string format. Actually this I already do from Xojo.
In m1b I insert the Byte array from an imageview.
I try to convert this m1b into a string in the myStringa variable and then convert it back into a byte array in m2b.
At this point I would expect m1b and m2b to be the same but both ways are different.
Where am I doing wrong? Can anyone recommend me a solution?

B4X:
Private Sub decodButton_Click
Dim myBitmap As B4XBitmap = ImageView1.GetBitmap
Dim m1b(), m2b() As Byte
Dim myStringa As String
Dim conv As ByteConverter
m1b = ImageToBytes(myBitmap)
myStringa = BytesToString(m1b, 0, m1b.Length, "utf16")
m2b = myStringa.GetBytes("utf16") 'convert to bytes
If m1b<>m2b Then
xui.MsgboxAsync("First bad conversion","!!!!!!!!!!")
End If
myStringa = conv.StringFromBytes (m1b,"UTF16")
m2b = conv.StringToBytes (myStringa,"UTF16")
If m1b<>m2b Then
xui.MsgboxAsync("Second bad conversion","!!!!!!!!!!")
End If
myBitmap = BytesToImage(m1b) ' OK only for m1b
toImageView.SetBitmap(myBitmap)
End SubIn m1b I insert the Byte array from an imageview.
