Just use plain ASCII characters. Then try again. If in doubt, your page has a different name that you intended, but that is nothing your users will care about, you can display whatevertheheck you want *on* the page.

Bear in mind that the page name is a class name in C#: so if you call your page anything which isn't legal as a C# variable, then VS will refuse it. The most common fault is to try using a space or a dot: these terminate variable names so are illegal in the class file name. Basically, stick to A-Z, a-z, and 0-9 and you'll be fine.
