Android Question Help to convert from unicode

[Thomas Philip C]

Hi All,

I am new to basic 4 android and i currently have a problem .. below is my code

data = c.Decrypt(data, kg.key, False)
datas=Bconv.StringFromBytes(data,"UTF8")

the issue is that it gives my result in unicode

eg

\u0054\u0068\u006f\u006d\u0061\u0073 instead of "Thomas"

Any help will be appreciated.
Regards,
Thomas

What you are seeing is the original string. This is the actual value stored in the encrypted bytes array.

You can use the code I posted here to unescape your string: http://www.b4x.com/android/forum/th...results-i-cant-read-hebrew.27461/#post-159533

Hey erel ,

how would i convert free text to unicode points ( the reverse of this process)

i.e

Thomas to \u0054\u0068\u006f\u006d\u0061\u0073

Here:

Sub UnicodeEscape (s As String) As String
   Dim sb As StringBuilder
   sb.Initialize
   For i = 0 To s.Length - 1
     Dim u As String = Bit.ToHexString(Asc(s.CharAt(i)))
     sb.Append("\u")
     For i2 = 1 To 4 - u.Length
       sb.Append("0")
     Next
     sb.Append(u)
   Next
   Return sb.ToString
End Sub

thanks i was somewhere close to it with my codes. was figuring on how to pad the extra zeros..

Sub EscapeUnicode(s As String) As String
Dim sb As StringBuilder
sb.Initialize
Dim i As Int
Do While i < s.Length
Dim c As Char = s.CharAt(i)
'need to change to unicode here
sb.Append("u\")



Dim codepoint As Int = Asc (c)

Log(Bit.ToHexString(codepoint))
Log(codepoint)
Dim str As String
str= Bit.ToHexString(codepoint)


sb.Append(str)
i = i + 1
Loop
Return sb.ToString
End Sub

thanks again. much appreciated.
