Cannot search in other language

Hi,

I install ”Events Search For The Events Calendar” in a Chinese website, and found that when I search in Chinese character, the plugin only display results which match the first character. For example:

If I search for “回” (<–Chinese character), the search bar will display event which start with “回” in titles, but cannot display other events which also contain this word.

“回xxxxxxxx” <–OK
“xxxxxx回xx” <–doesn’t show up

would you help me check this problem?

Thanks~

Hannah
