QueryBuilder returning different results than XPath "debugger" for Chinese character search

[b7wilso]

I am using QueryBuilder to do a search.  It works with Latin characters, but as soon as I do a search with Chinese characters it is not returning any results.  I turned on logging for com.day.cq.search which allowed me to pull the XPath query that it is attempting to run.  The weirder thing is that when I copy that query over to http://localhost:4502/crx/explorer/ui/search.jsp (the "debugger") and use that, it pulls back three results.  Would appreciate any help that anyone could provide.  For what it's worth we are on AEM 6.1, SP 1.  I will provide a log a Chinese search (that only works in the "debugger") and log for the English version of the Chinese search that works in both places.
