B4J Question [BANano]: [SOLVED] How to UTF8 encode strings for URL querystrings?

'convert a map to a querystring
Sub Map2QueryString(sm As Map) As String
    ' convert a map to a querystring string
    Dim SU As StringUtils
    Dim iCnt As Int
    Dim iTot As Int
    Dim sb As StringBuilder
    Dim mValue As String
    sb.Initialize
    
    ' get size of map
    iTot = sm.Size - 1
    iCnt = 0
    For Each mKey As String In sm.Keys
        mValue = sm.Getdefault(mKey,"")
        mValue = mValue.trim
        mValue = SU.EncodeUrl(mValue, "UTF8")
        mKey = mKey.Trim
        If mKey.EndsWith("=") = False Then mKey = mKey & "="
        sb.Append(mKey).Append(mValue)
        If iCnt < iTot Then sb.Append("&")
        iCnt = iCnt + 1
    Next
    Return sb.ToString
End Sub
