Special Character in Subject Field of Discussion Forum

Question

I am creating a new discussion, in the subject when i enter "Portal Discussion?" then it gives error that special character is not allowed. But i want to use the "?" in the subject at the time of creation.
After creating the discussion i can edit the same thing with special characters, then why SharePoint is not allowing to enter special character at the time of creation.

It seems that SharePoint will allow the Title of the discussion board to remain with the special characters, but the actual URL will not be allowed and will strip them from the final URL.  SharePoint Manager easily shows this, btw.
So, there are probably many different ways to get what you are looking for, but one way could be to have a Linq query look for all Discussion Boards on a given site and then return the Title and the DefaultViewUrl, which the latter could then be prefixed by
the SPWeb.Url to give you something like "Testing? , /" for the title and http://mysite/Lists/Testing/AllItems.aspx (assuming
that is the actual default view) which you could then use as the final URL for your hyperlink in your web part.
In the code snippet below you can see the Linq query (which I assumed from your post that you need to query to find the Discussion Boards) and a simple DataTable that you could then use to populate a repeater or you just omit the DataTable and
enumerate the results from the query yourself:
var linqResults
= from list in oSPWeb.Lists.Cast<SPList>() where list.BaseTemplate
== SPListTemplateType.DiscussionBoardselect list;
DataTable oDataTable
= new DataTable();
DataColumn oDataColumn_Title
= new DataColumn("Title", typeof(string));
oDataTable.Columns.Add(oDataColumn_Title);
DataColumn oDataColumn_URL
= new DataColumn("URL", typeof(string));
oDataTable.Columns.Add(oDataColumn_URL);
foreach (SPList oSPList in linqResults)
DataRow oDataRow
= oDataTable.NewRow();
oDataRow[
"Title"]
= oSPList.Title.ToString();
oDataRow[
"URL"]
= oSPWeb.Url + oSPList.DefaultViewUrl.ToString();
oDataTable.Rows.Add(oDataRow);
oDataTable.AcceptChanges();
