Restrict issue creation with certain symbols

[Phil Evans]

Hi.

I want to restrict creation of issues from portal with certain symbols in Summary and Description.

I can put Simple Scripted Validator on workflow creation with

!issue.summary.value.contains("«") && !issue.summary.value.contains("»")

and it works, but how do i use this restriction only for portal request issues creation?

Or please advise how can i use this in Behaviours?

After changing to "wiki style renderer'',  i am facing same issue. 

Only the existing file customer can view in case exist in the issue but customer can't view newly added file.
