Adding "AaÃáZz" to ts base file so it can be translated and editable

In Assistant (and perhaps others) in preferences > font i can see the string "AaÃáZz" as an example.

I suggest making this string translateable in the ts files (maybe base ts file) so that translators can write a string that is better for they language.

Like in my language i might want to write "AaÃáZzÆæØøÅå".

And make the string editable so the user can change the string to what ever.
