Hello...

just wanted to ask if this is intended behaviour in SWT that any string
containing a null character is broken at that point and not displayed
in a swt widget (checked with Text and TableColumn, though was displayed
as empty box in StyledText as I would expect it).

regards
Christian

Christian, I am not sure whether I understood your problem exactly. In
many cases, SWT does not accept null string due to the platform
constraints as many of the platforms does not support accepting it. For
that reason, it is valid to pass an empty string ("") instead of null
string.
Please elaborate your problem if this hasn't answered your question.

Christian is asking about support for non-null non-empty strings that
contains the unicode character at code point 0 (zero). Likely there are
limitations here because of platform issues as well, i.e., the null
character is often used as a string terminator...
