ArialUnicodeDemo.zip

Hello Benson,

In order to display Chinese characters, you should do the following:

1. Install the ArialUnicode font on your machine.
2. Set the Font property of all TextBoxes that will display Chinese Traditional characters to ArialUnicode.
3. "Feed" UTF-8 encoded text to these TextBoxes.
4. All of your clients that want to see the Chinese characters in their web-browsers should have ArialUnicode installed on their machines, because the browser will use the font to display these characters.
5. The ArialUnicode font will be embedded in an exported PDF file, so people that need to view ONLY PDF files will not need to install the font.

Here we are speaking about Chinese, but ArialUnicode contains all alphabets on Earth, so this applies to any other known language. You only need to have the text encoded in Unicode, so that the ArialUnicode font will work correctly.

I am attaching a Solution with two projects -- a WebSite and a ClassLibrary. In the ClassLibrary project I have put a very simple report with a TextBox with ArialUnicode set as its Font property (Style->Font) and with UTF-8 encoded Chinese text. In the WebSite, there is the WebViewer that will show the report. You may need to refresh the WebSite's assembly references (Bin folder) to point to the Telerik DLL's on your computer.

Give it a try and tell us if it does not solve your problem.

Dear Support,

I installed ArialUnicode font (Control pannel->font->add...) which downloaded somewhere with size ~23MB. I even reboot my pc. After openning your sample project, the Chinese in the textbox looks fine and I can see ArialUnicode font in the property window. Then I run the project, but the Chinese in IE browser cannot display properly. I verified that the default encoding is UTF-8 and no matter what encoding I changed, Chinese codes still display wrongly.

Question:
1. Any more hints on my situation?
2. For RadControls (no Telerik reporting) to display or work with Chinese characters, do I need to install ArialUnicode?
3. Why only Telerik reporting needs this unicode font to work with browser? (IE originally supports UTF-8 and I only need to display 1 type of Asian language at a time)
4. I used other ASP.NET reporting controls and never heard of using ArialUnicode for Asian language. Is it specific to Telerik reporting control?

Thanks for your advice.
Benson.

AreTheseTextsCorrect.zip

Hello Benson,

Up to your questions:

1. Can you send us a screenshot (to support@telerik.com) of your browser running our sample project and displaying Chinese incorrectly? We will also appreciate a screenshot of the Visual Studio designer showing the Chinese correctly so that we can compare them. Since the designer shows the Chinese correctly, we assume the problem is in the browser. Also, send us a screenshot of the Chinese in an exported PDF file. Is the Chinese in the PDF correct? I am attaching a screenshot of the Chinese text on our browser. Can you verify whether it is correct or not?

2. Arial Unicode is not directly connected to a single Telerik product. We simply suggested it, since it contains all possible languages and "plays nicely" with PDF files.

3. Reporting does not absolutely need it, but we suggested it, since it is free to use and has many benefits (there is no need to install Asian and Eastern European Font Packs on the clients' Adobe Readers, for example). Also it is a Unicode font. If you want, you can send us the original Chinese font that you used and the original Chinese text that did not display correctly and we will try to reproduce your problem.

4. No, it is not specific. We simply suggested it. As I already mentioned, if you send us your font and your original text, we will make an attempt to reproduce the problem that you have and solve it.

Once again, we are very sorry for the inconvenience that we caused and we are looking forward to the files so that we get this case resolved.

Here is the list of files that we will be happy to see:

A screenshot of your VS designer with the Chinese text.
A screenshot of your web browser with the Chinese text.
A screenshot of your PDF file with the Chinese text.
Your original Chinese font.
An excerpt from your original Chinese text.
If possible, a screen with how this Chinese text should appear.

I am attaching screens with some text. Verify that they are correct.

All the best,
Rossen

Hi Benson,

Thanks for the files. Up to your questions:

We recently found a problem with IE6 which doesn't understand correctly the encoding of the received response. The issue is already fixed for the service pack which will be available later this week. To ensure that this is the same problem, please, try to view the report either with IE7 or Firefox 2.x. The Arial Unicode font should be installed for the text to appear properly.
The .pdf document which is generated by the Reporting tool embeds the fonts that are used so the users which view it do not have to install any fonts.

Best wishes,
Chavdar
