In theory all characters are allowed. But you did not tell us what you tried, where you tried it, or exactly what errors or problems you encountered.

I'm sorry not to be precise enough. I have tried exactly this password:

Wl1xttb-.!G6N${>-T^>[o}tg

And? Tried it where? What happened?

We have no idea what you are doing, so unless you explain in detail there is no way we can suggest a possible solution.

OK, I tried to set a new password in my user account for this forum after receiving a temporary password. When I tried to save the password I got following error message:
Your password contained text that was not compatible with our system such as script or server directives.

In general, it's (at least) letters and numbers; with at least one lower case and one upper case letter, and a number. Minimum length of 8 (?). You go beyond that, then you're dealing with devices that may have differences in real or virtual keyboards.

I tried following password: Wl1xttb-.!G6N${>-T^>[o}tg

As you can see, the password uses characters from a typical English keyboard.

There are no hard-and-fast rules that everyone must obey when it comes to passwords at all, much less an "approved character list". Different sites - and different applications - will enforce different policies which may involve:

* Password minimum length
* Password maximum length
* Numeric characters required
* Upper and lower case required
* Special characters (i.e. non-numeric, non-alphabetic) required
* May not contain words in a dictionary (so no "my%password" or similar)

But don't have to.
Strong passwords are important, but they are not easily remembered, so they can reduce security considerably: the '"post-in-password" stuck to the side of the monitor' syndrome.

It's up to you what to do - though estimating password strength can help users by encouraging them to use stronger ones^* - the really important thing from your side is to ensure that you store it properly, rather than trying to force a user to strengthen his selection. That's more complicated than you might think: Password Storage: How to do it.[^]

* My bank does this: it rated mine as "Wow! Now that's a strong password!" But I have no idea what my password is: my password manager deals with that, not me!
