Language Characters

Syntax: list or range of characters, as inside REX []

The Language Characters setting controls what characters constitute a language query. Query terms composed entirely of these characters are considered language terms, and have Word Forms processing applied. The syntax is a list of characters (no separation), and/or a range of characters; the same as a REX character class (without the brackets). The default is \alpha\'\x80-\xFF, ie. alphabetic, hi-bit (for UTF-8) and apostrophe (for contractions). For best results, all characters that could match part of a Word Definition expression (here) should usually also be listed in Language Characters.
