Problem with using Turkish characters

Hi...

We have a problem in our solution using .Net2008 C#.

We using EWS. Then when we upload document to Livelink using our project, if document name include Turkish character, after uploading when we look at Livelink GUI the document name has modified.

Forex: Document name we give on our solution include some of characters like "???ÜÖ" then it replaced on Livelink GUI like "IGS" and other characters deleted.

We change following section on web.config file like "Default" = "UTF8"

</appSettings>

but problem not solved.

We search the file for determining our problem, with given name that we used on our solution. But no search result coming.

Thanks for any reply...

Hi Ghasem,

What EWS call(s) are you making to perform the upload?

I can try testing it here when I get a chance.

Hi Kyle

This is the code below :

DcmService.OTAuthentication otAuthentication = new OTAuthentication();

OTAuthentication otaDcm = new OTAuthentication();

baglan = Login.GetLogin(Form1.userName, Form1.passWord);

otaDcm.AuthenticationToken = baglan;

CntService.ContentServiceClient cntServiceClient = new ContentServiceClient();

DcmService.DocumentManagementClient documentManagementClient = new DocumentManagementClient();

CntService.OTAuthentication otaCnt = new CntService.OTAuthentication();

otaCnt.AuthenticationToken = baglan;

AttributeGroup attributeGroup = documentManagementClient.GetCategoryTemplate(otaDcm, 39393);

Metadata md = new Metadata();

AttributeGroup[] list = new AttributeGroup[1];

list[0] = attributeGroup;

md.AttributeGroups = list;

DataValue[] Catvaluess = attributeGroup.Values;

FileInfo Files = new FileInfo(path);

dosya1 = listBox1.SelectedItem.ToString();

if (listBox2.Items.Contains(dosya1))

{

MessageBox.Show("Already exist.");

}

else

{

TextBox[] txt = panel1.Controls.OfType<TextBox>().ToArray();

for (int i = 0; i < txt.Length; i++)

{

(((StringValue)((DataValue)(Catvaluess[i]))).Values[0]) = txt[i].Text;

}

ContextID = documentManagementClient.CreateDocumentContext(otaDcm,2000, dosya1, null, false, md);

FileInfo inFile = new FileInfo(path);

FileStream inStream = new FileStream(path, FileMode.Open, FileAccess.Read);

FileAtts fileAtts = new FileAtts();

fileAtts.CreatedDate = inFile.CreationTime;

fileAtts.ModifiedDate = inFile.LastWriteTime;

fileAtts.FileName = inFile.Name;

fileAtts.FileSize = inFile.Length;

string objectID = cntServiceClient.UploadContent(otaCnt, ContextID, fileAtts, inStream);

Hi Ghasem,

I am seeing the same sort of thing you arewhen testing with the Turkish characters you mentioned.

I’ll look into this further to seewhere the problem lies.

The byte stream of my sample filenamestring (?????_inputdata.txt), once inside LLServer, is:

DD D0 DE DC D6 5F 69 6E 70 75 74 64 61…

If I save the same string in Notepad withUTF-8 encoding and then hex edit the file, we see this byte stream (with theBOM):

EF BB BF C3 9D C3 90 C3 9E C3 9C C3 96 5F69 6E…

Lining these two up we see that the first fivespecial characters become garbled, however, the rest of the filename is leftalone:

????? BOM????? ?[DD] ????[D0] ????[DE] ?????[DC]?????[D6] ??[5F] [69] [6E]…

[EF BB BF] [C3 9D] [C3 90] [C3 9E] [C3 9C][C3 96] [5F] [69] [6E]…

This clearly shows that the Latin-1equivalents for the characters are being passed in by the web service insteadof the UTF-8 encoded versions that should be passed.

With further digging, we found a knownissue with the LAPI binaries used by the web service with UTF-8 encoding.

Using the patched binaries, this issue nolonger occurs.

The bug number is LPO-645.

I’ve asked development if they arecomfortable with making this particular one-off patch public (as it isuntested).

If so, I’ll try to get it on the Knowledge Center for you to download.

If it cannot be made public, then you willneed to open an Open Text Customer Support ticket (referring to this forum),noting bug LPO-645 and that you’re looking for the fix for your versionof Content Server (Livelink).

If you do obtain the fixed LAPI_NETp.dllfile, you will be replacing the one located at<OTHOME>\webservices\dotnet\les-services\bin.

As soon as I hear back from development, I’lllet you know.

Regards,

Hi Kyle Can you contact with your company for the dll file to problem I had?

Is there any build-up for the problem ?

Thanks & Regards

Hi Ghasem,

The patches will be publicly posted, butwe need to wait for the appropriate processes to complete before I can give youa link.

Once that is done, I will post the link.

We've now posted the patch that will allow full UTF-8 support for 9.7.1 + .NET EWS development.

You'll need this patch:
https://knowledge.opentext.com/knowledge/llisapi.dll/Properties/17686480

The patch contains a new LAPI_NETp.dll file.
This file should replace the file of the same name in the <OTHOME>\webservices\dotnet\les-services\bin directory.

When backing up the old LAPI_NETp.dll file, make sure that the backup does not end in ".dll" or IIS will try to load it (e.g., call it LAPI_NETp.bak).

Regards,

Kyle
