I am using Net Library, and the MailParser Module, to receive emails at my application.
Everything seems to be fine when using English Letters in body, however when there are Greek Letters, the message seems to disappear.. (m.body = empty)

I have tried both from Google email, and Hotmail but the result is the same..
Does pop support UTF-8?

From the Basic4Android Log i found out that with Google email, the Content-Type charset is UTF-8 (the body however seems to be encoded64),

(Email received by google email, includes the greek message)
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: base64
PGRpdiBkaXI9Imx0ciI+z4DOsc65zr7OtSA8YnI+PC9kaXY+DQo=



(Email received by hotmail email, includes the greek message)
and when using Hotmail, it is "iso-8859-7" and appears as
<body class=3D'hmmessage'><div dir=3D'ltr'>=E5=EB=EB=E1=E4=E1!<br> =

I Think the problem is here :

Sub HandlePart(Headers As String, Body As String, Msg As Message)
If Regex.Matcher2("Content-Transfer-Encoding:\s*base64", _
Regex.CASE_INSENSITIVE, Headers).Find Then
'we are dealing with an attachment
Dim filename As String
Dim m As Matcher
m = Regex.Matcher2("filename=\s*q([^q]+)q".Replace("q", QUOTE), Regex.CASE_INSENSITIVE, Headers)
If m.Find Then filename = m.Group(1) Else filename = "attachment" & (Msg.Attachments.Size + 1)
Dim su As StringUtils
Dim out As OutputStream
out = File.OpenOutput(dir, filename, False)
Dim data() As Byte
data = su.DecodeBase64(Body)
Log("file saved: " & filename & " (" & data.Length & " bytes)")
out.WriteBytes(data, 0, data.Length)
out.Close
Msg.Attachments.Add(filename)
Else If Regex.Matcher2("Content-Type:\s*text/", _
Regex.CASE_INSENSITIVE, Headers).Find Then
Msg.Body = Body
End If
End Sub

When there are greek letters, the Header is Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: base64

When there are only english letters it is Content-Type: text/html; charset=UTF-8

So it when there are greek letters, it thinks there is an attachment, and saves it..
