See the screenshot. This happened when a CVE was copied from a word document and put in the Search box, it produces no output and is confusing for the user.

The URL itself on submit will look like:

https://www.cve.org/CVERecord/SearchResults?query=%F0%9D%97%96%F0%9D%97%A9%F0%9D%97%98-%F0%9D%9F%AE%F0%9D%9F%AC%F0%9D%9F%AE%F0%9D%9F%B1-%F0%9D%9F%AF%F0%9D%9F%AC%F0%9D%9F%B1%F0%9D%9F%AE

You could either use accept-charset or convert the string to ascii on submit.
