For the filenames, that's the default behaviour, all except \0 and / . 
However, you can restrict it only to UTF8 valid sequences with the 
"utf8only" property. That can only be enabled at dataset creation time, 
I tend to enable it nowadays. See also the "normalization" property.

For dataset/pool names, only a subset of ASCII is supported.
