I want to have it checked a form field "name". In addition I have "Letters or punctuation" set. In German there is the letter "ß" and "ä", "ö" and so on, this he must admit. How can I achieve this?

Hello Steffen,
we are currently investigating the possibilities to create specific charset validations.
We hope to provide this in the very near future.

I have the same problem, which probably exists in any non-English language. I thought that in 2016 we finally overcame this problem thanks to UTF-8?
This is a real bummer and should be considered as severe flaw.
What happens to our clients of Eastern European countries and languages? Would Теодор considered to be a wrong entry?
It was never mentioned that form-validator only works in English.

Hi All,

Unfortunately Unicode consists of huge amount of code tables for different languages. So what is letters in German is something very different in Chinese.

That is why we currently support the base ascii letters only. As supporting all possible languages will increase enormously the validator code base and also page download and response time.

We are however hard working to improve this in future updates. We are looking for ways to be offer support for charset selection, so you can choose from which charset your letters should come from.

Greetings,
George

Thanks for the quick answer, George.
As a coder I understand the problem. But users on the page we are currently re-building will not understand that his name Hans-Jürgen has "special" characters in it. The letter "ü" is as common as any other. Since we need the validator for people wishing to be added to the weekly newsletter list, which is sent to thousands of recipients several times a week, this is not an option.
Can I add some code manually to make it at least working for German? (In future this will not be enough. Even in Germany or Austria you have names like Renée Petrovič or Sándor Petőfi. (Mind the Hungarian "ő"
