Hi,
if I input 65428 for city, that is what I get. In your GOOGLE WEATHER4 demo, you have "Taipei" as default. If I enter "65428" in WEATHER4 demo, the city is shown correctly, the text is chinese though. :-(
The HTML code for the 'broken' character is ü and the unicode is ü
Like I said, the city name is shown correctly in your GOOGLE Weather4 demo. If I choose language 'de' in the module I have the problems with the Umlaut.
Don't know if these come across correctly in your browser, but the characters would be, among others: ä ö ü Ä Ö Ü
Unicode: ä ö ü etc. Maybe this link will help, if shown correctly in your browser:

Regards and thanks for the help,
