Microsoft Excel files can sometimes contain phonetic (furigana) strings.
See <a href="https://support.office.com/en-us/article/PHONETIC-function-9a329dac-0c0f-42f8-9a55-639086988554">PHONETIC</a>.
This sets whether or not the parser will concatenate the phonetic runs to the original text.
<p>
This is currently only supported by the xls and xlsx parsers (not the xlsb parser),
and the default is <code>true</code>.
