Rich Text Box character set

Question

When I copy, for example, the word "Çamlık" from a web page into a rich text box (forms application) at runtime, it is displayed as "?aml?k". Is there a setting in the richtextbox control or form or application to fix this? If not, what is the "socially acceptable" method?

Answer 1

What font is your textbox using? When I use the default font in a tiny test program, it works fine:

using System.Windows.Forms;

class Test
{
    static void Main()
    {
        RichTextBox tb = new RichTextBox();
        Form form = new Form();
        form.Controls.Add(tb);
        Application.Run(form);
    }
}

That's cutting from Chrome on Vista and pasting into the above program compiled and run from the command line.

Do you get question marks immediately after pasting? Do you have any other processing in your text box? What does the above program do for you? Which browser are you using?

Answer 2

I think that could be due to the fonts setting on the richtextbox which doesn't seem to have support for the character range that you are pasting.

Try setting the font to something that supports the unicode range of characters, you are pasting. Try Arial Unicode MS & see if that works.

EDIT: On a side note, does the site that you are copying text from have things in unicode?
It is possible that the site might have text in ASCII & use a specific font to render it for a specific language.

If you have a custom paste method, be sure to paste as DataFormats.UnicodeText as opposed to DataFormats.Text; as the latter is ANSI only which would give you the '?' characters as a replacement for the Unicode chars.
