Solr query with space (only) gives error

I have a frontend that uses Ajax to query Solr.

It's working well, but if I enter a single space (nothing else) in the
input/search box (the URL in the browser will show

    ... index.html#q=%20

In that circumstance I get a 400 error (as there are no parameters in the
request), which is fine, but my web page stalls, waiting for a response.

If, however, I enter a semicolon ( ; ) rather than a space, then the page
immediately refreshes, albeit with no results ("displaying 0 to 0 of 0").
Also fine / expected.

My question is what is triggering the " " (%20) query fault in Solr, and how
do I address (ideally, ignore) it?
