The recent documentation formatting changes introduced the navigation panel on the left. However, due to the length of the query options navigation title these could overlap with the documentation paragraphs. This commit removes the underscores from the navigation titles of the query options, so browsers can break them into multiple lines. Additionally, the "SET" and "Query Options for the SET Statement" pages are merged to save some more space for the query option navigation titles.

<indexterm audience="hidden">UTF8_MODE Query Option</indexterm> UTF-8 support allows string
|
|
functions to recognize the UTF-8 characters, thus processing strings in a compatible way as other
|
|
engines.</p>
|
|
<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>
