Android Question utf-8 from email body

[rosippc64a]

Hi All!
I am reading emails with MailParser. I got an email, what is encoded as utf-8.

This is a multi-part message in MIME format.
--------------2AA4A1963CC8BFB384908ACE
Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: 8bit

LÁT6ÁR
-----------------------------------------
This is in a string variable. I save it into an sqlite database. When I get it back from datbase, the string looks like the same, not as I would, as a normal utd-8 string, like this:
------------------------------------------------------------------
LÁT6ÁR

------------------------------------------------------------------
How can I convert the string into a real utf-8?
thanks in advance

Programmers should never use notepad. Use a decent text editor such as Notepad++ that allows you to see the encoding.

How can I convert the string into a real utf-8?

Once you load a string there is no more any encoding involved. Encoding is only relevant for converting bytes to a string and vice versa.

thank you for quick reply, but what would be the reason of that, when I say: edittext1.text = this_string, then there is no correct characters appeared?
There should be: "LÁT6ÁR, no "HĂrlevĂ©l". As if the android wouldn't know that it is an utf-8 string?

So interesting.
At the screensave there is a character, utf8 code is C3 A1. This is 'á'.
I found it in an utf8 charset table also.
á c3 a1 LATIN SMALL LETTER A WITH ACUTE
ok. so my text is utf8, but android think, it isn't.
This text I can convert to good string with this

        Dim bc As ByteConverter
        Dim sBody As String
        If Headers.ToUpperCase.Contains("UTF-8") Then
            Dim sBody As String = bc.StringFromBytes(Body.GetBytes("iso-8859-1"),"UTF-8")
        End If
        Msg.Bodytxt = sBody

Then this text was utf8 or iso8859-1?

When I see this text in windows, then I should set the character coding to utf8 to see correct chars.

 

[Erel]

Dim sBody As String = bc.StringFromBytes(Body.GetBytes("iso-8859-1"),"UTF-8")

This line can cause some of the characters to get corrupted.

You should save the data to a text file and upload it to the forum.

As if the android wouldn't know that it is an utf-8 string?

The OS doesn't know anything about the encoding. It uses the encoding that you specify or the default utf-8 encoding.

Here is the message saved directly from the gmail (in windows). But the file signature can be seen at the beginning of the file isn't relevant for the Mailparser, because it got the text as ordinary string.

 

[Erel]

I don't see any issue with the text file.

Tried it with:

Log(File.ReadString(File.DirAssets, "original_msg.txt"))

I can see all characters properly including non-ASCII chars such as: LÁT6ÁR

 

[rosippc64a]

Yes, I can see also. I tried, but in mailparser there is no that file, only a string containing that content. I write and read back and all chars remain the original, what android can't shows as a normal utf-8 text. I leave previous solution till will be better.
Thank you!
