Textual content

A string of characters is considered textual content if it contains one or more characters from the letter or number categories of Unicode. This definition applies to the string as a whole, regardless of any other characters the string might contain.

A piece of textual content is considered to match another if, after removing leading and trailing whitespace and replacing remaining occurrences of one or more whitespace characters with a single space, the two pieces of textual content are equal character-by-character, ignoring any differences in letter casing.

A piece of textual content is considered included in another if the latter includes any consecutive sequence of characters that matches the former.
