Special characters in Tcl.�
-Try strings starting with a -Bad and strings containing [BAD], {, \077, and $Bad. For user input, [BAD] should never be evaluated, \077 should not be turned into a ? and $Bad should not be interpolated. The string -Bad [BAD] \077 { $Bad should be valid user input, should pass through the system unaltered, and if it isn't that's a bug.

then the quoting for the field is incorrect. (It's not clear whether this
should be considered an error but given that data for text fields can
come from various sources if it's text it should be properly quoted
and we should not rely on input validation to prevent XSS security
holes.)
Whitespace input.�Check that whitespace is not considered valid input for a field
if it does not make sense. For example, the subject of a forum post is
-used to construct a link and if it is " " it will have a link of
-<a href="..."> </a> which would not be clickable if whitespace was allowed as a valid input.
