Search fails if 1st character is not ASCII
On my https://ui.customsearch.ai/hosted-page, when I search for 'λογος' I get error: "Unable to execute your query."
If I search for 'logos' I get results.
If I search for 'logos λογος' I get different results -- pages with 'λογος' in them.
Looks like a bug: first char must be Roman or ASCII character?
