UTF-8 support allows string
functions to recognize the UTF-8 characters, thus processing strings in a compatible way as other
engines.</p>
<p class="p">You can use the new query option, UTF8_MODE, to turn on/off the UTF-8 aware behavior. The query
option can be set globally, or at per session level. Only queries with UTF8_MODE=true will have
UTF-8 aware behaviors. If the query option UTF8_MODE is turned on globally, existing queries that
depend on the original binary behavior need to be explicitly set to UTF8_MODE=false.</p>
