IOptions::UnicodeFilterRanges Property
Syntax
IDL
__property BSTR UnicodeFilterRanges;

Indicates Unicode ranges that are of interest when filtering. 

This is used to help the filtering algorithm to distinguish text from non-text data. It is only used as a hint in the algorithm, so if the text extraction algorithm detects text in another language with a sufficient level of confidence, it will return that text even if the language was not selected.
