Providing a link to the site you are accessing with the web viewer would help the FileMaker Techs see this for themselves if you can provide such a link...
Thank you for your post, and I apologize for the late reply.
I am unable to replicate the problem with FileMaker Pro 11.0v3 on Windows XP (SP3). The web page shows the Chinese characters. The Chinese characters also display properly with FileMaker Pro 11.0v4 on Mac OS X 10.7.2.
Any other information you can provide may be helpful.
I tested it on every PC in our Office. They are nearly the same.
WinXPSP3 german, 32-Bit, Filemaker 11.03.
On none of this is this working with the integrated webviewer. I had a contact with a german filemaker guy. He told us, yes this is a known filemaker bug. No it will not be fixed with version 11.03. It will be fixed with version 12 and a new webengine. So, in my mind, i bought a new product with an very old browserengine.
