Hi Britt-Marie.
It took me a couple of days to find your discussion of this matter with a colleague of mine at CA.
You probably will still have this email communication from May 2016. Just let me know if not and I’ll resend it to you.
In this communication the colleague essentially stated, that the application needs to validate the user’s input prior to invoking the proxy. And explained that if this is a Gen client, you potentially could use the VERIFY function to make sure only characters supported by code page 278 were allowed as input. For a handwritten client, you’ll most likely need to use javascript code to perform the validation. HTML 5 also has some new validation capabilities.
Since this handling is done outside of CA Gen there isn’t any proposal we provide. A Google search though for “how to prevent invalid input on web page” results in a lots of suggestions.
I did get back to you, since you did create a “Question” – not a “Discussion”.
While this is understandable since you wanted to ask for feedback from the other community member, we, CA, want to make sure every question is answered and marked as such. Therefore I contacted you and would like to ask for your agreement to mark this question as answered.
If you want to leave an open entry within the CA Gen community, please create a “Discussion” item, that is supposed to stay open.
Best regards
Hillrich
