dtSearch .NET Standard API 2021.02
Indicates Unicode ranges that are of interest when filtering.
UnicodeFilterRanges indicates the Unicode subranges that the filtering algorithm should look for. For example, if UnicodeFilterRanges is set to 1 and 8, then the filtering algorithm will look for characters from U+0100-U+01FF and U+0800-U+08FF
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.
In .NET and COM, UnicodeFilterRanges is a comma-separated list of integers, each from 0 to 255, indicating the Unicode subranges that the filtering algorithm should look for. Example: "1,8". Options
